From lying down to sitting up, 69, or even sideways resting your head on her inner thigh helps deal with neck ache. You can also use her hands to spread her labia, giving you better access. Leave your experimenting and playing around for the beginning. That depends on the girl. I had no idea what I was doing, the guy was hardcore pressuring me, and I just felt so grossed out about it- he expected me to put my mouth down there…WHAT?! Alternatively, you can penetrate her with your fingers. If she likes that, you can move on. I had heard other girls talking about them in the locker rooms, whisper about it in the back of classrooms, and one time Mike asked if I would give him a BJ! And there are real emotions involved. You need to start out slowly. The first is neck ache, which can be handled by switching position. Until she orgasms would be good, but she might ask you to stop before then. Move your tongue in an up and down motion, or side to side. Start your tongue action, and see what kind of movement elicits moans of pleasure, then stick to that one for a while. What works for one might not work for another, and what worked last night might not work tonight.
