This starts off as something that seems like a bad idea, at least by Hollywood movie and "traditional" standards.

The idea that a woman, married or unmarried is desiring to have sex with a male friend, invokes thoughts of jealousy and betrayal. Maybe there has been some real world examples of things going badly, and the feelings are justified.

Or may be its a hidden human trait that we just don't understand how to properly use.

It seems that this could be beneficial if done using the right communication. The human mind seems to go into a mode when two people meet and there is sexual attractions between them. This could be physical or mental. The feelings typically are powerful and cause distractions during the encounter. I believe this happens for both males and females. There is nothing new about this knowledge, it's most likely that every human has felt this.

In Hollywood films and in real life, if the participants act on this, it seems to create immediate passion between them. I won't say "love", because I think too many people confuse love with infatuation. The feeling are typically short lived and either die out completely or cause an imbalance in feelings of attraction for one side or the other.

Scholar and research scientist Alfred Kinsey, made a discovery that people can have mutual sex among casual peers. While he is famous for his early research on human sexual nature, he also was known to have all of his employees and research assistants agreeable to have sex regularly between the others. This worked well to provide a positive environment. Kinsey did not exclude himself from this theory and research. He actively engaged in many sexual preferences to help him understand the research.
Another note about Kinsey's research is that this all occurred in the 1940's and 1950's. A time when even mentioning sex in pubic or private social gatherings was considered TABOO.

Based on his research, it seems that sex occurring between men and women who are friends (or even co-workers), is a huge benefit to the human mental and physiological state. Initial communication about intent, is most likely the key to keeping the negative outcomes from developing.

Alfred Kinsey's research was really super progressive at the time. I think that even now such a study would be rather non-standard.

I will divide my opinion into 3 statements

Statement 1.
Sex should happen when there is a need for it. Sex is a basic need and therefore must be satisfied on demand.

Statement 2.
If there is a sexual attraction between friends, then they are highly recommended to have sex.
At the same time, do not forget that sex is a basic need. If sex happened between friends, this does not mean that someone owes something, or friends announce in such a way that they are a couple.
The note. People become a couple based on more than just basic needs.

Statement 3.
If one of the friends is married/in a relationship, then a third party enters into the "sexual relationship" between the friends. More specifically, a friend is a third party.

Why? Most of the time a friend spends with his partner / husband / wife, they have a common life, common interests, a common energy field.

And what to do? I believe that sex with a friend should be coordinated with a partner, since every other sexual contact brings its own component to the relationship of the existing couple. Accordingly, the decision on such "implements" should be made by both partners. In this case, family relations will be preserved and developed (regardless of the decision made).
Also, I believe that decisions should be made on the principle of benefit for the relationship of the couple.

Regarding the benefits of sex between friends / colleagues for the mental and physiological state. I think studies like this showed a benefit since sex happened:
1) between people who know each other well,
2) and it was regular.

The same effect is achieved in family/couple relationships. At the same time, if a couple has sex regularly, this sex is suitable for both partners and evolving, then it is unlikely that there will be a desire for sex with another partner.
I do not deny that there may be hormonal surges caused by various factors that may cause the desire to have sex with a friend or stranger. But in this case, it is worth remembering the "internal energy field" and treating it with care (see Statement 3).

Statement 3 makes a good point.

I hadn't thought about it as one person being single and the other being married. In that situation, I agree that the establishment of rules to not interfere with the marriage or family absolutely needs to be in place.

In my mind, it was if both people were married to other people, as I had seen in the Kinsey data. But even in this case, the same rules you mention would need to be applied.

The sexual energy is very important. I like that you mention it must not be wasted or overlooked.

Yes, you are right - Statement 3 must be applied in that case as well.

I'm glad that my point of view makes sense

Different people have different opinions on the question of sex between friends. Some consider it possible, while others do not. Everyone should decide for themselves what works best for their relationships and personal values.

I agree that sex between friends can be normal if both parties clearly understand their feelings and intentions. It can be a way for two friends to enjoy each other without creating serious obligations.

I think sex between friends can lead to disagreements and conflicts between people. At the same time, I understand that everyone has their own point of view and experience in this matter.

Sex between friends does not align with church teachings and moral principles. The church calls for sexual activity to be limited to marriage and for spouses to remain faithful to one another. We believe that sexual relationships should be based on love, commitment, and respect.

I believe that sex between friends can be normal if it happens with the consent of both parties and without pressure from anyone. However, I also urge for awareness and respect of personal and partner boundaries. It is important to understand that sexual relationships can have emotional consequences and affect friendship dynamics. Therefore, I would recommend careful consideration before engaging in sex with a friend to avoid damaging important friendships and emotional well-being. I do not consider sex between friends to be an inherently wrong choice, but it should be a conscious and well-thought-out decision.
