I am an 18 year old female and recently lost my virginity. My problem is that while having sex, i feel a very uncomfortable pressure in what feels like my bowels, like i'm going to have to go to the bathroom. I often feel this during digital penetration as well. It is very disruptive to sex and i often worry that i am going to lose bowel control. The second time i had sex, i noticed what seemed like a small stain in my underwear which seemed like some kind of anal leakage. I have no history of gatsro problems, except for acid reflux. I am very petite, and my boyfriend is not, if that means anything.
What could this be? It is causing me to be very anxious and is also preventing me from really enjoying sex. Any advice would be helpful. thanks!
