We met when I was 14 and were together for about 8 months. He ended up getting married to someone else.
A noble thing to love so unselfishly. This is true love indeed. Perhaps there is yet hope. Why not look him up? Maybe he's single now?
not always true yes, and it doesn't mean that they are gay either. It may be true that most guys are primarily or exclusively motivated by sexual interests, but this is not universal.
I have a few platonic male friends, but two of them are married, one is unrequitedly in love with a good friend of mine, and the other two are ex boyfriends. I have yet to befriend an unattached guy that didn't view me as a potential sexual partner, but I'm sure its possible.
If there is physical attraction and you hit it off, naturally a guy might view a girl as a potential partner. But under the same circumstances a girl would naturally see a guy as a potential partner. I think there is a tendency for guys to be primarily or exclusively motivated by sex in their relationships with girls, but it's not universal by any means.
