His hair piece fell out

honestly idk how to feel right now. On one hand it’s not that big of an issue but on the other hand he really never told me he wears fake hair. Like we’ve been dating for 4 months and I never knew. Like literally up until I was having sex last night I thought I was dating a guy with long hair. I always told him I liked his hair. He just smiles and says thank you. Never allowed me to really run my fingers through it though which I just respected even though he’s always playing with mine which he says he likes because it’s really curly. We were having sex last night and I was starting to feel it strongly (like emotionally and physically) so I just had to grab his sexy hair. It wasn’t just one part that fell out, it was almost his whole head. Like his real hair was very short and he just kinda tried to hide it by flipping me over and apologizing. Then quickly brisked off to the bathroom and came back in with a scarf wrapped around his head almost an hour later. He just fell asleep and didn’t really say anything. He hasn’t called me yet.
