Receiving oral help!

Do any of you ladies feel uncomfortable when someone goes down on you?! I've only been in 1 serious relationship and he was my only sexual partner. We were together for almost 6 years and he only went down on me once because it mades me so uncomfortable! I want to like it though but I'm extremely self conscious when it comes to down there! Well now I'm trying to get back out there and am extremely nervous and anxious to have another sexual partner! Help!
