When giving blow jobs and hand jobs, how do I know if they like it???

Just experiment. Fondle his balls gently, lick the tip, move your hand up and down in a circular motion(kinda like twisting) and deep throat lol... Just talk to him. If he starts grabbing you or rubbing you, moaning he likes it...

um if you see there eyes rolling back and there back arches and they start talking dirty. also if your giving head they will grab your head. that's what I usually do

ASK.

It's hard on here to describe the good things you can do when giving a blow job or hand job because of the limited space and/or having the answer removed The very best advice I can give you is to just ask your guy to guide you to what he likes best since every guy responds differently. What will work good for one guy won't be as effective with another. Usually, when I'm enjoying something she's doing I'll thrust some, like I'm asking for more of that. Another is to put my hand on her head and when I pressed down a little that means the same thing. There's no way you can make a mistake unless you and your boyfriend don't communicate about anything or it's just some hook up guy that you don't even know very well. I've never accepted either of those from a girl I haven't known for a long time because I'm just into doing sexual stuff with random girls. But what I said here should help you the most. Before you start just ask him to respond so that you know how you're doing, whether it's good, great of it sucks. lol!

how fast they come is usually a good indicator. how heavy they're breathing is also a good one.

look at his face, is he looks bored he probably is but if he's like leaning his head back or closing his eyes, kinda smiling or open mouth and breathing heavily then he definitely is. or you can just ask him if it feels good! if it doesn't feel good he can then tell you how to make it better

They're really into what you're doing. You should be able to tell by their movements and what they're saying. If they're still like a dead man they're probably not enjoying it.
