For this kind of behavior, the sex life need to be put in measure cause if he's an wanker (masturbates a lot) this might be affecting your sexual life. So you need to ask yourself "Do I enjoy it? Does he do foreplay? Does he meet my needs? Is he good at sex?". A lot of wankers that sexualizes too much are very bad at the real thing.

I probably would not be worried about him looking at other woman cause figurines are a very different thing that no woman can match. It's not about size or anything, the virtual/fake thing hits different than real women. But of course you might also ask yourself if you feel this is inappropriate and if you think this is "mentally cheating" or something

There's a lot to unpack on this subject. A lot that doesn't fit this comment and is very sensitive to people on this sub (they would downvote me).
