Blow jobs?

Main thing is to do it all. enjoying it and showing that you like it will be the biggest turn-on. When it starts getting towards the end though. concentrate on hand action and in-n-out action.
Most sensitive area (men's clit) is underside of shaft (part facing down). just under the head. Work this a lot but do not over-stimulate (just like a clit.)

Well first of all you want a girl who will try a variety of techniques. The keys to any sort of oral is build up and attitude. The attitude is all about what happens before you actually start. Every guy wants you to want to do it. They don't want to ask for it.

Once you know what your guy likes (either forceful or submissive girl. maybe even both) either push him down and go for it or act all innocent at the start. Then start slow. You want them to get worked up by the time you are really going for it that way you aren't tired towards the end and believe me it does happen. If you are going 100mph at the beginning you probably won't stay there. but if you start at 25 then move to 50 and so on. you will have a strong finish.

The last major thing is being aware and listening. one way or another he will let you know what he likes and wants more of. but don't just stick to the same ole things. You have to make him be with out something for him to appreciate it when he gets it back.

It all depends on the girl. If she really enjoys it then she will choose to prolong it as along as she can. Simultaneously, the guy will start to get aroused and excited and he may reciprocate it by either performing an oral or on the girl or stimulating her with a finger. The final outcome could result in a blissful orgasm for both.

I'm trying to think & put this into words.
Have you ever done this before? Do you know what to expect at the end?
Well I guess start by licking the head & the hole. Not too much time on the hole as it's sensitive. The more saliva the better. I'm not saying spit on it just let saliva drool down your tongue & on to it. Just up & down. You can use your hand too if you don't want it too far back in your mouth. Kind of keep your hand at the base so you only go that far down & you can also use your hand up & down. Maybe like eating a dripping Popsicle on a very hot day. I don't think that you can be bad at it as long as you watch your teeth. If you need to kind of curl your lips around your teeth until you get the hang of it.
There is nothing wrong with saying (after a few minutes) let me know when your close so that he doesn't "finish" in your mouth. Just turn the ending into a H.J.

Just using the tongue at first slowly licking under and around the sides. Slowly up and down. That will drive a guy nuts. Don't start the actual sucking until later on.

use both hands. slow and fast. and some tongue action !
