cant get wet for sex?

so ive been with this guy for almost 2 years now, when we first started dating, all he had to do was just brush his hand across my hip and pull me into a close snuggle and id be dripping wet for him and beg for sex on the spot, last year i took birth control for 1 month (progestin only) and stopped taking it, i was still able to get wet, but not as much as i did. now for the past few months i cant get wet for sex at all, and my bf is so used to me being sex ready as soon as he pulls his pants down, no foreplay needed. so now he pulls his pants down, walks up to me and tells me he wants to fuck, i get into position, and im dry as fuck with him trying to push it in for a good 5 to 10 minutes, and as soon as a little bit of wetness arrives and hes able to slip it in, he goes for it and its super fucking painful, but as he gets in as deep as he can (hes 4 inches sometimes 5ish almost 6 depending on arousal and really thick), right up there it hurts the most and i have to gasp in pain. he thinks its super hot because it makes him feel good about his dick, but he usually ends up making small tears and my vagina gets sore and swollen. the last time we had sex he FINALLY used lube to get me ready, swabbed it all up in there and on himself, and it slid in easily, no pain, till he got to the deepest point and thats when the horrible pain hit, when he hit that spot. but anyways, my question is, how can i restore my wetness because im getting tired of being embarassed for not being wet enough for sex, he thinks it because i dont find him attractive anymore, which is not true, i love him to death and find him very attractive. i just dread sex now, because i know i cant get wet, and im gonna be embarassed, and we are going to be struggling for 5 to 10 minutes with him trying to get his dick in, and smashing it against my vagina to "make me wet" its a big turn off for both of us. i just want to restore how wet i used to get. advice to do so?
