I need some tips for how to pleasure myself

You could try rubbing your clit and it's not really weird that you and your friend please each other.

Ask her if she has any preferences. She may have some ideas you haven't thought of yet. Talk about it and think of things to try. I use the split finger method on my wife. I rub up and down both sides of her vulva to get her going then begin touching her clit as I'm doing that. You can play with all those lovely parts in there to see just what feels good for you and her. Licking them usually does a great job. If you/she likes it, inserting a finger or two or however much you want inside her/your vagina may do it. My wife likes it when I circle her cervix with my finger tip and kind of play with it ---- sometimes. Sometimes she doesn't like that at all. She never liked me to rub her G spot but some girls love that. So everyone is different and you just have to experiment.
