I don't know where you got that idea,
She got that idea because there are so many guys here that think just because they sign onto a sex/dating site that pussy is going to just fall into their laps... they wish!!!
I agree with you though, there are alot of women on here looking for women and I think that the majority of them do that for their husbands/boyfriends.... JMO but there are alot of women on this site who actually DO enjoy being with other women.
You should be able to do a search of man seeking woman and bring up what you're looking for. Most women looking for women on this site have their profiles set to read, female looking for female. So don't look at those... there are a shit ton of them! You just have to wade through them!!
Good luck!! And like sugar said.... check out the other aspects of this site... have fun!!
