I need some explanation

Ok guys, so when I masturbate I have a clear distinction of when I actually orgasm but when I have sex it’s very pleasurable and after that high is over and my boyfriend cums I don’t feel like I came but there’s fluid that shows I did?? I get a heavy feeling in my stomach and I’ve squirted before. So, I don’t know if I’m having an orgasm when I get that feeling🤷🏽‍♀️ and I always want to go another 2 or 3 times because I don’t feel like it’s enough, is that normal??
