How to pleasure a guy without sex?

I am 16, and I was wondering what is the best way to plesure a guy without having to have sex, and if I give him a blowjob, how will I know if I am doing it right

The answer is DON'T. You will lose respect for yourself and him. Do you really think you have to do that to keep him? If so he is not worth it. A real man will NOT make you feel like you have to do that. What you propose to do is part of the inevitalbe spiral that will lead to sex. I've known too many people who's live shave been ruined. Don't do it. Find someone who respect you for you, not what yo can do to them.

If you feel ready to take the next step then the best way to pleasure someone is to talk about what they like. You don't have to go to blowjob right away, you could start by just touching him and maybe giving him a handjob. It's normal to be curious about sex and to want to pleasure your partner. He probably would also like to pleasure you that's why you guys should talk about it. Of course, you are not obliged to do anything you don't want to do and somebody who loves you wouldn't pressure you into doing something against your will. I think it's also important to explain to your boyfriend that you don't want to have sex that way he knows what your limits are.
