Can you finish more than once in a session?

So ill start with im a trans man so I already have no amab equipment myself and don't plan on bottom surgery and even then itd be different. Ive been active with men awhile and have always seen and heard guys can only cum once and guys who can do it more or even stay hard after are rare and such. I assumed this was true and it problem still is for sure however my new bf stays hard after cumming which is hot but with no bc right now I have yet to let him go back in me or keep going (been doing piv but wanna try anal too so maybe then I can idk)

anywho yesterday we did our fun and he finished and I kept rubbing which ive done before but it can be over stimulating so I tend to watch his body and stop. Well I kept going and it was fun and he did move a lot like normal but never exact hand up stop movement I normally take and he came a second time on him and my hand and it was hot but I was legit shocked I didnt think or really believe it could actually happen. (Tho maybe my insecurities add too cause I already feel,like making a man cum is a big honor as is)

So i do wonder how often it can and does actually happen? Is he just lucky or is it more common than people tend to believe or know? Or maybe people just dont talk of it?
