Very much so.
I can do either. If I use lube, it is coconut oil these days.
Wasn't a serious relationship as she was my friend's GF. We did have sex a few times. My friend knew. It was his idea!
We do mutual all the time. Sometimes she has a couple of orgasms before we have sex. Sometimes we both cum masturbating.
One FMF. It was awesome. actually twice with the same couple.
