My boyfriend and I are waiting to have sex of any kind (oral, etc) till we get married. In the past, guys I have been with would get turned on and they would claim to hurt, because they couldn't "relieve" the hardness. I asked my current boyfriend, if he hurt, when this occurred. He said no. Is this normal? Why would some guys experience pain and not others?

I think that's normal. I think those guys who say it hurts, are pretending that. I think they want to have sex with you. If worse to worse happens a guy can masturbate to relieve the hardness. I'm a guy and I never had such a problem. :)
