I just started having sex a few months ago. At first everything was fine (very little pain, except the first time), but then she went on birth control. Soon after she started, she became very tight! Now it takes at least ten minutes for me to penetrate, and it still hurts her. I'm a bit over 6"circ, but she took me without too much pain before. Anyone heard of this? She's too embarrassed to ask her doc about it, but we are going on our honeymoon soon and I don't want her to be in pain the whole time. Thanks.
