My bf and I have been together for nearly 2 years, we love each other and have a great bond. The only problem is that we are both tops and it has really put a damper on our sex life. We enjoy oral and rimming a lot, but he's only topped me 3 times in the whole 2 years. He is strictly top, and I don't mind being a bottom, just can't get through the pain. He's not super big, 7 length but pretty thick. Here is a pic of me actually getting it in one time. Any advice ?
