Caution: Hand jobs before sex. HELP lol

Caution before you read lol

Ok so I've been getting comfortable with giving my boyfriend a hand job and playing around with his penis and balls. He seems to really enjoy it when I like to tease myself before I take off my pants. Like he'll kind of thrust a bit as if putting it in where my vagina is as I still have him in my hands. Then I'll get to the point to actually removing everything but still play with him down there before I fully enter. The whole teasing turns me on a lot. I'm gonna be honest i wanna be more confident about my hand work but need more ideas because he seems to last a lot longer lol.
