Well, I would agree with the "having sex with someone you're not attracted to". Man, I wouldn't want to ever marry or have sex with someone I'm not physically attracted to, and I do think that's a big part of who you choose to be with (and it's also important to maintain yourself to attract your partner too)
Regarding the difference in character, has there been a case where the personalities outside the bedroom were in exact sync, but only when it came to sexual preferences were different? - like the tender versus rough?
And regarding sexual organs, this is one thing I have managed to find in medical coloumns of people asking for advice, apparently this is something people can do something about. Apparently it is like Nigel powers says "it's not the size, it's how you use it"?
Anyways I need to research on what to do if the vagina's too small and it hurts her, or it's too big and she doesn't get satisfied. Anybody else have this problem?
