I'm 18 and I just tried to have sex with my boyfriend of 6 months. It was my first time and it was excruciatingly painful. It felt like I was being ripped in half. He only got half way in and he had to stop because it hurt so bad. There was plenty of foreplay, and we used lube. I feel 100% comfortable with him, and he was very understanding and caring about it. I really want to enjoy this with him but it's unbearable pain. Will it always be this way?
