Ok so i have been having sex with my fiance for about 9 months now. We have tried all sorts of different things from toys to positions, but I can never complete an orgasm. I can feel it start, but once I get close to that point, I lose it. The guy I was with prior to him could get me off with hardly any effort, but with my fiance I have to be on top every time to even feel him... Maybe it has something to do with the fact that my ex was bigger.. I'm not so sure. I just can never get off and when I don't it makes my fiance feel guilty because it's super easy for him to get off... I just don't know what to do anymore....
Re: Is it normal....
If the rabbit is working for you, maybe get a smaller vibe for him to use on your clit while you're having sex. Or try different positions. I've heard doggy-style tends to make smaller penises feel larger because of the angles involved.
ETA: And Google kegel exercises and try them. Having more control over your inner muscles can help with g-spot orgasms.
Honestly, keep masturbating is my advice. I was never able to orgasm during sex before I started regularly masturbating. Now I do almost every time. I think it is more about knowing your own body and what feels good to you than anything else. Once you know that, you can show him.
Does he get you off in other ways? Oral, manual, etc.?
