He didn’t have balls??

So I recently started dating this guy and we had sex for the first time last night. I sucked his dick and was playing with his balls then we fucked for a while but he didn’t finish yet so he asked me to suck him off. I started going ham on his dick and he asked me to play with his balls again so I went to suck on them and... they weren’t there??? Like literally NO BALLS DOWN THERE. I didn’t say anything and got him to cum but I’m very confused. Ive never experienced anything like that??? Can someone explain please!
