Is normal to not masturbate ?

Hello, I'm 18 and I don't masturbate often ( well let me not lie 😂. I haven't in years.. since I was like 15). I was in a 2 year relationship and around a couple months before I turned 18, we got sexually active. I lost my virginity to my ex and it lasted like 3 minutes because we were both scared that I would end up pregnant. We ended up sticking to stuff like oral sex and he's the only one who touched down there. I mean of course I do when I wash up but not in a sexual kind of way. If that normal ? Can anyone relate? When my girlfriends hear that I don't masturbate they think I'm crazy and that I need to explore and see what I like? People often are shocked

What do you think ??
