The most important thing to remember, especially if you’re just starting to learn how to give great head, is to keep things interesting. Especially when you’re new to something, as soon as you find something that works you’re prone to wanting to repeat the same thing over and over again.
But don’t do that.
Even the greatest sensations fade over time.
Something that felt amazing for him the first time, will surely not feel as great if you keep doing it for ten minutes straight.
This is just how we work as human beings; what gets repeated gets boring.
So remember to vary yourself all the time while you’re learning how to give great head.
Change your technique.
Vary your position.
Speed it up.
Slow it down.
Keep it fresh!
