Is it normal that i love the pain i get after sparring?

I take jujistsu once a week and I often playfully spar with friends when they come over, and I love the pain I get the next day, whether that be sore muscles from working out or bruises from landing hard or taking a hit. I do not self harm and usually do not like pain. But waking up sore the next morning gives me this happy feeling inside (it sounds stupid but I can't think of any other way to describe it). I usually tell people I am sore and that I don't like it when they ask but truthfully it's a great feeling to me. Is that normal?
