So my boyfriend and I have been together two years. I'm definitely more versatile than he is. Because of my size, I end up bottoming alot, I think cause I have more experience, and because he's in pain for a few weeks after I fuck him. Needless to say, I get to top once every two months or so. Any tips on how to stetch him open for a more permanent basis. Once we get started he's fine, but hell to recuperate. Thanks for any tips and advice.
