Hello all, I am a 22 y/o female and I have been on antidepressants since a young teen. So I’ve always had a hard time during sex. Recently I’ve been hooking up with a guy whose goal is to make me finish and I just am not sure if I have or if I’m even able to?? For a female, what does finishing look like or feel like? If he uses a vibrator, I get to the point to where I’m shaking and squirming but it just kind of feels like a roller coaster that doesn’t go down and eventually just gets uncomfortable. How do I know? Any advice on how to finish? Please help!
