how do i overcome my fear of genitals?

hey, so my boyfriend and i are both sexually active but we don't get to see each other often because of long distance. when we do get together, in terms of sex and communication we have a very healthy relationship and we aren't afraid of telling each other what we do and don't want. i have a slight issue, however- i'm really repulsed by looking at genitals. i can touch them with minimal issue (i.e masturbation and whatnot) but i want to be able to get over my fear of looking at them so our experience in the bedroom doesnt have any major hurdles. i know this sounds like i'm doing this solely for my boyfriend, but he's fully aware of the issue and has never had a problem with it. i'm just curious to hear from people who mightve had this issue in the past.
