I'm 24 and have been in several serious relationships over the last 6 years. With each relationship, sex has been good for the first few months, but seems after awhile with each guy, I don't feel as vaginally tight as I was in the beginning. I have tried kegals, which haven't helped much. The guys I have been with have all been of at least average size (and felt large in the beginning of relationships. I'm starting to get paranoid in my current relationship, because I feel like I'm not gripping him at all. When we were together at first, I felt really tight and could feel everything. He says it feels good when I ask, but I haven't directly asked him if I feel tight/loose down there, but lately he seems to be avoiding sex or we don't finish because he has to work or he's too tired. I don't know if there's something wrong with me, or maybe my vagina just adapts to a guy's penis over time, and it's less tight because I'm not as nervous?!?
