Burning... down THERE

My boyfriend and I have been together for a while now, and we are sexually active. Lately, I’ve been feeling like we are rushing into sex before I’m all naturally lubed up and ready to go as of a result I’m left a little raw as tonight when we tried to have sex it almost felt like it was burning. We are both clean of STD’s and STI’s, so that’s not a concern, but I’m curious if anyone else has had this problem and knows how to fix it
