Let's be blunt, someone tell me how to get my boyfriend to have sex with me.

Sounds as if he has still to work through his own inhibitions. If he says he wants to accommodate and learn to bottom then he should practice alone in the shower and in relationship with you too. The alone time with a small dildo helped me tremendously as a top wanting to learn to be a good bottom.

I found that it takes a real man to be a great bottom, but there is no substitute for a well trained (self or otherwise) truly versatile man. mmmm

Best wishes as you seek to grow... Bring him here. Encourage him to explore.
Establish the agreed boundaries and go/grow for it!!!
