Okay, So I am 18 years old and I have been dating the same guy for about two years. We have had sex probably hundreds of times by now, but just recently, i've started going numb during sex. A couple months back, I'm guessing my boyfriend grew some and it actually hurt to have him inside of me, but it still felt good. Now, however, I am not really feeling anything. I feel pleasure during foreplay, but when he goes in i can feel barely anthing. I am really concerned. Is there something medically wrong? I'm going to the gyno soon to see, but I just wanted some opinions on to why this is happening. Someone help please because, to be honest, this really, really ***** and is putting a strain on my relationship.
