Do men really like giving oral?

I, 20f was dating a guy 21 and some months into our relationship when we got physical he'd always start it. Not because I didn't want to, but I was still shy. Every time he started going down on me (I never asked him to btw I always let him do whatever he wanted lol) eventually he'd put his tongue on my butt as well, which was... Interesting ngl he was my first physical partner. He ended the relationship with me some months ago for various reasons (that I'm not really sure about tbh) and I always had the feeling that he didn't really like me that much (I was going through low self seem on myself and my body at that time), even though he was really sweet and caring all the time, not only in sex but every time we'd meet I never really had a problem with him. So my question is, do men really like giving oral to any woman or is it more like an intimate thing? Because this one wouldn't stop.
