My fiancée and I are a lesbian couple and lately my fiancée hasn't been able to cum. We're 29 and 28, and my fiancée is of the vulva having variety of woman. No shade, I know it varies from lady to lady and that's just how her set up is.

My fiancée has always taken a long time to cum, she's on an SSRI (Zoloft 70mg) but that hasn't stopped her in the past, it's only made it take longer... and it's obvious she enjoys the journey.

Lately though she gets overstimulated, I guess? We've been having sex more often, probably because it's warmer and we've been more active. We both have big libidos but I think she experiences sexual pleasure on a level that I just don't. She gets to a point where she can't speak or even register that I'm speaking, her eyes roll back, and it used to be that after some time this would lead to an explosive orgasm eventually but now she'll just stay at this point until she gets too overwhelmed. She'll close her legs, squirm away from me, move my hand, whatever, because she can't say anything... sometimes now I'm able to tell when she's ready to tap out, but if I ask if it's too intense or if she wants me to stop or keep going she doesn't respond with anything coherent. At that point I'll usually stop anyway and let her get reoriented. She'll either thank me or complain, lol.

My point is, she can't cum anymore. We're content with our sex lives but... would both like her to cum again, I'm sure. She both takes a long time to orgasm and then becomes too sensitive to finish, is there some way to help that? We've talked about it and she doesn't have any ideas.
