So This More Of An Embarrassing Question To Ask So

So this more of an Embarrassing question to ask so about a week in a half ago or so I was masturbating and was about to cum but I didn't bcuz I got interrupted so it's almost like I held it in and since then I've been feeling the urge to urinate at least thats just what I thought it was bcuz I thought It was is it really possible for sperm to stay in your penis that long until you realease it I just figured it would come out alittle bit on its own or alittle bit whenever I peed?
