My boyfriend and I have pretty decent sized dicks. My only issue is I'm a lot more sensitive than he is. It's not that he desensitizes himself with masturbating or anything, I just think he's less sensitive than average. He's a top and it takes a lot just to get him to cum and I feel bad because the sex is great for me, but I think it could be better for him. I want to know how I can give him an out-of-this-world orgasm. Suggestions?
