I am agree with what most of people have written: Sadly it is accepted (and seing something hot) than a women be bisexual while on Men it doesn't exist: most people tend to think they are gay who fears go out.
Also sadly it is related with promiscuity.
If we mix with the view about sex than toon of women have had : 1)something fun when young but after having kids or become older they tend to be sexless.
2)A way to take the control of the relationship : they choose when and where.
3)A chore
...
(I believe this is something which is very important to talk about when the relationship is beginning)
Anyway, of course it is my view and I am no judging anyone, I find than having sex with other person (without care the gender) is cheating which I hates (as I would feel horrible if my patner cheat me and probably I could no forgive it, I think if I do is the same).
Of course I am taking about me, my experience : if my patner try to use sex to control me and/or the relationship, I would stop it the first time: a second will make the relationship ends.
If it begins to be a chore, we would talk about it and trying to find a solution.
I can't support feeling than sex is as a business or forced.
On both cases I prefer to take care of my needs (a wank is a lot better than that)
I believe a couple should be able to talk about everything, which includes fears, kinks, things as bisexuality, what kind of relationship (close, open) and set the boundaries (of course we change constantly and the boundaries can be changed consensuated), but if one boundarie is broken, the trust is lost.
And yes, I bet most of you think than thinking this way it is very hard I find a women and begining a relationship which last,ok : I prefer be alone than feel on a jail.
Nowadays I have some feelings about a guy, I don't know where it will led but whatever happens I am no going to act as people things than it must be : everyone lives their life as they choose, I don't critize them (of course they are a few exceptions as it is a power relationship where one only lost, is beated), I don't allow be critized :
-if they are people important of my life I had no issues to talk with them, explain, clear their doubts..but if they choose I am no good for them: I am sorry but bye.
-if they are people who had no relationship with me, I ignore
