Skinny Girl On Top

I was recently with a new partner and when I went to my go-to easy-to-orgasm position, he went flaccid.

Let me explain. I'm a pear shaped 5'9 who weighs about 130lbs. Not a lot going on up top, so I though perhaps he disliked his view, but apparently it's worse. My being on top actually hurt him!

He explained that my pelvic bone was bearing into him. I'm 35 and have never run into this complaint before.

Some girls may say to write him off if I know what I like and with him I can't have it, but I like him and want to get creative and try again, but I need help.

Any other slim couples out there needing to avoid the pain of knocking boney pelvic bones? My partner jokingly suggested a pool noodle to separate us. Send help!
