I need help

Hello lovelies! I need some help. I’ve been having issues with my sexual relationship.

Every time I try to have sex with my boyfriend, I start off wet but can’t stay that way and it’s hard for me to get myself wet. I don’t know why this is happening. It’s not that I don’t want sex or anything I just can’t stay turned on and I have no idea what’s going on. I can’t go see an gyno because I don’t have insurance and they are super expensive in my area.
