Excatly. Can, does not have to.
I see friendship as meaning that the feeling of friendship are the ones prevaling, not sexual attraction.
Q: How do you distinguish between sexual attraction and sexual tension?That being said, there is also our intellectual abilities to compartmentalize, which can help to keep us from acting upon that tension or attraction. We can CHOOSE to be non-sexual. But the attraction/tension is still there, and if one of the friends becomes romantically involved with someone else it can create strains in the other friend. Jealousy is also a part of our genetic makeup, after all.
Apart from that, it sounds a bit like you think that because we are wired to reproduce, sexual attraction almost certainly must develope between two persons of opposite sex, regardless (more or less) of the situation. (When talking hetereosexually orientated people, obviously.) But why should that be the case? We do not copulate non-stop. We do not
feel like having sex with every person we meet, or every person we come close to. At least,I do not think so.
I think it can happen if a person happens to be needing sex - but still not nessecarily.
As for jealousy being part of our genetic make-up I do not really believe that. I think it is expectations and habit of thinking.
I know both men and women who are not jealous, and for my own part I have learned that if there is no fear of loosing and no neglect of my needs, I am not jealousy. I have experienced this. He could have sex with another women right next to me, and I did not care. I am not sure monogamy is a default either, but a choice.
What do others think of this?
