how to pleasure a guy? We are wanting to have sex

Hi there. Just be yourself, don't pretend that you are someone else. Focus on what he wants and also don't be afraid of telling him what you want and what you like during the sex. Also, you should know that there are those erogenous zones for men and I am sure that your boyfriend is having it as well, like all others. Maybe you should try with a passionate kiss, after this, you should massage his ego, telling him all those things that he wants to hear. Touch him and use your hands and your mouth as well. This is all normal and you will get used to doing this. Also, every sex will be much better because you will get to know your partner better in the sexual life.
