Yeah, my girlfriend doesn't like regular porn either. She preferred those Tumblr porn gifs (that have since been banned from Tumblr). I found this out when i first gave her a cathinone-type stimulant. We sniffed the stimulant, I went to the bathroom, and when I came out she was looking at porn gifs on Tumblr, while rubbing one out with a little pink lipstick sized vibrator. I was definitelty surprised. But unlike porn videos, these Tumblr porn gifs had a kind of artistic feel to them, most of them were greyscale (ie, not in color but rather black and white, which gave more of photography vibe). It's funny, I didnt find that particular cathinone to be especially prosexual but I guess she did (she has little experience with drugs).
Unfortunately, her openly looking at those gifs is what gave me the mental green light to later turn on porn videos when we did some long sex filled stimulant binges with some truly pro-sexual cathinones. But in time it became apparent that she clearly wasn't a fan of actual porn videos and it sort of made things awkward later. I guess I thought that if she liked those gifs than she'd like actual porn, but I was wrong.
In anycase, after this recent incident where I accidentally caught her masturbating while watching the tv show Euphoria and reading erotica, I actually bought her two paperback erotica books (with erotica short stories). I did this because she felt embarrassed and perhaps ashamed, so I wanted to reassure her that I didn't see anything wrong with her doing that. So I bought her some books.
The problem is, the erotica books I got her were pretty lame. One was called "Best Women's Erotica" version 3 or 4, the other I forget. I did a fair amount of research and those were the best I could find on Amazon (which allows you to read a sample). I must have read like 15+ samples before choosing the two books. I was going for short stories because most erotic is in novel format, or written as a series, and I had no idea which type she'd read. Plus, personally, short stories are the only type of erotica I'd ever read, but I'm a guy and more straight to the point than many women. Anyway, after getting the books I read through them and they weren't great, one of the books was especially lame. Don't think she's read either. Maybe the novel format would be better, if you have any suggestions.
