Self conscious

Chendrix@yahoo.com
Help please. This is my first post on here so I hope im doing it right. I have been dating my bf for a few months now and we've had sex plenty of times. The thing is hes a lot more experienced then me and I keep getting self conscious about different things like how I look downstairs and if im good enough at it or not. Its getting to the point where I dont even want to have sex. Thanks in advance
