I am a lesbian in a monogamous relationship, about to graduate college. I lost my orgasm; the last five times we’ve had sex I haven’t cum. During our latest session I could not achieve orgasm and my partner became very upset and frustrated. I think it is mostly directed at the situation and not specifically at me, but I also believe she blames herself and this breaks my heart. So my question is how do I fix this broken part of our relationship? And how can I get my orgasm back?! Please help!
