I am a 29yr old healthy woman. I have been in a serious relationship for the past two and a half years. Lately we, or I should say I, have been having problems in the bedroom. I have been having a serious problem when it comes to sex. I am only able to have sex for about 15 minutes. (ok this is embarrassing but here is goes) Meaning that I completely dry up. I love my boyfriend very much and love making love to him but this is becoming a real problem. He doesn't want to use lube and is taking this very personal. PLEASE help me!
