My boyfriend has now mentioned for some time that he wants to give me oral sex and I really do want to experience it however I'm not entirely confident with what my vagina looks like. He has come close to doing it before but I've pulled him back up because I feel like he might be a bit grossed out or his reaction may upset me. He's a lovely lovely boy and I know he wouldn't ever say anything to upset me and I know he loves me for who I am but I'm just very under confident with the way my body looks down there. Any advice?
