I remember the thread not too long ago where a huge number of posters had slept with both men and women.
There is a post today about an admission of bisexuality. I've always thought actually my preferences and sexual past are mine and if DH asked I would be honest but I don't feel he has a right to know as such. Don't really feel he has a right to control how I feel about anyone now either even though we are married (or me him). He has a right not to like my friends but not to tell me not to like them. We each have a right to our own friendships and feelings and past. If we have crushes/things start crossing the line it is a. Our business and b. our responsibility.
This is influenced by having been in a very controlling relationship before but given that some people would not want a relationship with someone bisexual or if they had perhaps had a huge long list of exes or maybe even were a virgin I wonder if that is actually disingenuous and actually if really people consider that partners should have a right to know what kind of sexual experience their sexual partner has had. Also how far that might extend? Is there a "right answer" or is it just different for all?
