Problem  for a intelligant woman(and a man too)

Smart woman are among us.They occupie important positions in modern society.State administration,military,science,education,and health depend on them.They make crucial decisions for us ,in our lives...But I will not talk about that because I think the question of a weman equality of rights was decided long time ago.I payed attention instead,to sexual life of a smart women.I start to admire beatiful,smart,high educated women in highschool.My female friends,teachers,colleagues have the same problem.Actally ,I had a problem with them-They didn't care about sex.It was really enjoyable to sit and talk with them about interesting subjects.We shared same interests except one,crucial,most important to me.Without consideration of age(mine or theirs) the problem was the same:i wish and will-they don't want or can't!Reading books I found pretty much similar cases especially between well known,celebrity people.for me,most inerested example of (mis)understanding between man and woman was relationship between Jean-Paul Sartr and Simon DeBovoir.Existencialist and philosopher Sartr does'nt need intgroduction.De Bovoir was one of a kind,sharp-sighted,inventive and beatiful woman at the same time.Eweryone who had red her work"Oppposite sex" knows what I mean.
They were best friends,simpathizers and co-workers but not loverws,in real meaning of that word.Sartr was intimate with lot's of other women,much less smarter or much less beatiful than Simon and she knew that.Nevertheless they stayed inseparable.But after Sartr's death,in his testament there was no place for her.All his work and possesion belonged to his last love(sexual partner or wife,I don't know that for sure).
I believe she was very disappointed and felt betrayal.But I think she never understood some basic stuff's about sexuality and human behaviour.Maybe she was asexual or too inhibitated to think about it.Sexual instinct is a very significant part of our life and we should not admit to ourselves to underestimate it.Any substitute for that kind of experience (and pleasure) is temporary and unappropriate.Therefore,it is not unusual to see proffesors and other intelectuals how abandoned their wives and families,just to be together with their female students.Mother nature is always smarte then smartest men on the world and wining at the end.
