I am a virgin, with limited sexual experience. I have never given or received oral sex, I am uncomfortable with my body, but I would be willing to try it. I wanted to know if the partner would notice any inexperience. In giving oral sex, the most important thing you can do is enjoy giving it. If it is fun for you it will be fun for your partner.
Men can tell if it is simply a mechanical act that the woman hopes to cut short.
Be playful with your tongue and lips, do not suck too hard and do not blow. Use your hands to pleasure your partner, as well as your mouth. Tell him to give you fair warning. In receiving oral sex, the most important thing when beginning in the receiver role is to focus on the pleasure and not on what the man is doing. Focus on how it feels.
