Sex daily

Me and my boyfriend see each other usually every day, and almost every time we see each other we have sex at least once. He told me he wants to have sex at least twice a day (he was kidding) but he has a high sex drive. Recently though I've been having trouble getting wet (even though I'm turned on) and it's really starting to just hurt down there. I swell up and I'm not sure if I'm getting enough recovery time. Is it unhealthy to do this?
