I think that called being a block wanting to have sex it's a big driver for mens motivation succeed in the world
I think men and women can be friends it just depends is that friendship truly valued by both peoples
If a man won't to sleep with his woman friend they cannot really be friends
And if a woman don't wish to hand out with you or have conversations which are two why and not just one way
That's a sign that both parties are not really friends that is if you are a man or a woman in any kind of friendship
Also men and women want to date people on their level
