Sex Help Needed

Hey :p I'm 19 and my boyfriend and I have been going out for about three or four months now, and we've started having sex. I find that I get sore and dry easily during, and needless to say, it puts a damper on things—my boyfriend feels inferior because he can't get me wet enough and I feel bad because my body isn't cooperating even though I want to. We've tried lube, but it doesn't help when it comes to penetration. If anyone has tips or advice, that would be awesome. ❤️
