This is a big mistake and in my opinion quite selfish. You need to keep that rhythm going, but start to gradually speed up and press harder as she moans louder. Heightened arousal, lubrication, and pleasurable sensations are all important whether or not she reaches orgasm. This will do much more to turn her on than just getting straight down to business. If a woman thinks that you are not into it, she is not going to be into it. If she wants you lick harder or have a pointier tongue, she will let you know. Also, you do not have to tolerate being suffocated or having your head squeezed by her legs, so use your hands on the inside of her thighs to remind her if needed. Start out slowly A classic mistake with oral is that you just dive in with your tongue flicking away at lightning speed. That depends on the girl. May you eat heartily and regularly! Some women cannot tolerate direct contact with their clitoris and need to have the area pretty wet for it to be comfortable. Move your tongue in an up and down motion, or side to side. If a man has not had a shave in over 8 hours, his razor stubble could approximate the grain of grit sandpaper, which is pretty abrasive. If your tongue starts to get tired, gently suck her clitoris or kiss around the vaginal area instead. Or let your fingers linger and stroke around her entrance to take advantage of the massive amount of nerves there. The best is when you can let yourself go and really eat her out. From lying down to sitting up, 69, or even sideways resting your head on her inner thigh helps deal with neck ache.
