<human>: To my girlfriend, sex means pain. She's a tiny girl and I'm a medium-sized guy, and once she began warming up to the idea of sex about a year and a half ago, we immediately ran into problems. I used to not be able to get inside due to the pain is caused her. Now for us, sex is her gritting her teeth and taking it until I feel too bad to continue. Highly and consistently unsatisfying for both parties. We've also repeatedly tried what her gynecologist suggested: ample foreplay, lube, and patience. At this point we've tried about 80 times with about 8 or 9 "successes", you could say.

My patience is running thin though. I love this girl and we've been through a lot. We have a great relationship in every other sense, but sex is extremely important to me.

A couple of months ago I bought what I thought would be the solution to our problem. After asking her permission, I bought an extremely unintimidating sex toy, set it up, explained it to her, and asked she try to fix our problem by, I dunno, shaking things up and making some room for me. My logic was that a toy can be used easily and leisurely, with no pressure at all to satisfy it.

Over the past two months, I've brought up my request a few different times (while I was in various emotional states, I'll admit). Still she hasn't tried. I've offered to be there, I've offered to not be there, I've offered to help and to not help. I don't know what to do. She says she agrees it's the best solution we have, but clearly doesn't like the idea. Well I don't like not having sex, and I can't stay in what is essentially a sexless longterm relationship.

Any advice from /r/relationships? Am I being unreasonable? Thanks a lot.
