Spicing things up with boyfriend

So Normally my boyfriend and I will do stuff in the car because we don’t have our own places yet and our parents are home all the time. (We are both seniors ) Normally I will give him a bj and just have a makeout sesh with him and that’s it. Idk what else to do to please him besides give him a bj and kiss him. Any ideas ?

We haven’t had sex but he really wants to but every-time we get together I have my period or last time I had an yeast infection so their is always something stopping us from having sex. Btw he DEFINITELY DOES PLEASE ME so I just want to return the favor u know if that makes any sense.
