Can’t get wet?!

Y’all I have a serious question. For the last month or so I’ve been having a hard time getting wet when having sex with my boyfriend. I love him and i do find him sexually attractive, sometimes I will feel very horny and I still can’t get wet. And because of this we use Trojans with lube and I’ll get wet after he puts it in, but when he does it can hurt. So, what should I do?
