I have a friend that was technically in an open relationship with this lesbian, they are both in their early 30s. They've been living together for 3 years now, they've not dated anyone else since they started dating despite their opened relationship, he pays the bills and all that and she recently started asking about making children. On top of that he is the first dude she ever slept with.

I do not trust women who claim to be "lesbians" and bisexual is meaningless at this point.
