Recent sex

Recently, my boyfriend and I have not been using condoms when we have sex and using the pullout method instead. We are in a committed relationship and we have both been tested for any STD's. Usually, when we use condoms, we have to keep reapplying lube every couple of minutes because I just dry up for some reason, even though I'm turned on and everything. When we don't use them though, I'm so wet for him. Does anyone have any idea why?

Another question is that he says that because I shave my pubic hair, the hairs irritate the head of his penis and makes it a little sore. I've tried shaving everyday instead of every other day, but it's the same way. I don't like to not shave because it feels uncomfortable for me, so I don't know what to do to help make it a better experience for him. Any ideas?
