Caugh my boyfriend and foundation?

So I recently noticed that my boyfriend has this backpack with toiletries but seems to be very discrete about the bag. On our second date I saw his skin tone didn’t match his neck and I asked him if he was wearing makeup? He said no and got all angry and said he “used” to go tanning. Then months later go by I notice his face skin looked like something was on it almost like foundation. I then saw his backpack inside of it had a makeup brownsery film around it as I looked in I found a brand new bottle of revlon foundation. He is very in to his appearance but not in a feminine way what so ever.
so what do I do? Ask him? Thoughts any one?
