I’ve been dating my girlfriend for about a year but I don’t think I’ve ever got her to orgasm. I feel like I can get her about 2/3 of the way there, but I’m missing that final 1/3 to get her over the edge. I’m not sure if its something wrong with my technique or what it could possibly be. When we first started dating, I tried to be really open and communicative during sex so I could understand what she liked. I think one problem may be she doesn’t seem to fully know what gets her there either because she has trouble explaining to me what I’m doing right/what I could improve on. I will say I’ve started to pay attention to her body language, and sometimes I get strong reaction but other times it seems like the same thing does nothing, and I can’t figure out why. Another problem could be how she tends to move around a lot (which I would say is probably a good sign) but it makes it hard to keep a steady rhythm or angle, and my arm burns out fast when she wants things super fast or consistent. Eventually I backed off trying to talk through everything because I realized my fixation on her orgasm was probably making her overthink it too, which doesn’t help either of us. I feel like I've tried most of the techniques but I'm not sure what I'm missing/doing wrong. Could anyone help me out here? It’s really bothering me and I want to do better. Feel free to ask me any questions whether its about what I do, technique, etc. Thanks.
TDLR; I feel like I can get my GF 2/3s of the way to orgasm but I struggle to successfully push her over the edge. Am I missing something or is it a issue with my technique?
