Hmm, yes if she does not masturbate I honestly think she might just not be that much into the physical pleasure, you may have to just take what you can get - even though you would be frustrated, she may not be. It’s hard for me to imagine, too! But if she enjoys the closeness and seeing you get off, your expectations may be getting in the way.
Even if she gets frustrated, she will probably have to figure out herself what works. It’s really good she is not faking, don’t push her to the point she feels like that’s the answer.
Can’t see the list but basing this on the comments - I have been enjoying the new Hard Quartet album and think you might like. Rock and roll, more or less.
Janelle Monae, any of the first 3 albums in particular, but all of hers flow well.
Run the Jewels, if they aren’t already in your list. Second album, but again, any.
Absolutely love the new Fontaines DC album.
