Is this abuse?

I'm not sure if these things that happened to me were abuse. They've bothered me for awhile, and I haven't felt comfortable talking about it to anybody. I just want to know if it was or not so I can at least get some clarity maybe.

I knew way too much about my mother's sex life as a child. She told me about the size of men she was with, things they did, things she liked, etc. I feel like this has affected me negatively when it comes to my relationship with her and in my own relationships. Is this considered abuse?

Also, a man my mother dated made extremely inappropriate comments about my figure when I was a young teenager. He would say things about the size of my breasts or my butt in front of my mother, but since he said it jokingly, she never said anything about it. He also would ask me to massage his shoulders, hands, and rub his head or back when I was younger. I didn't think anything about it when I was a teenager, but now that I'm older, I feel as though that was very wrong of him. When I told my mom that he made me feel uncomfortable, she took his side saying that I wouldn't be touching him if he made me uncomfortable.

There are other things that occurred, but these are the ones I want to talk about. I'm very confused about this and would just like someone's insight.
