I do not currently have a visible external OB. I recently had sex with my boyfriend after not being active for about a month. The next day when I was taking a shower I noticed something down there...oh how can I describe it? It looks like skin tissue that would cover a blister in your mouth. It was biege, and it was not discharge. Has this occured with anyone else? I'm thinking that I might have an internal OB on my cervix. Also I did and have in the past had some pain during sex. A couple of times the pain was so bad after having sex that I could not walk or stand up straight.
