when me and my boyfriend try to have sex, he is hard right up till the point when he sticks it in...am i doing something wrong?? it is both of our first time so we really dont know what we are doing but im sure there isn't really a wrong way.. we have tried so many times we had foreplay for 3 hours and it still didnt help. Im wondering if its nervousness, or maybe even a medical problem? Any other time he can get hard so easy, but when we get ready to have sex it ust goes soft! please give me some advice!
