Won’t go down

Okay so I have this little problem my husband won’t do oral we been married for about 2 weeks and I was his first he’s 26 I’m 22 he lost his virginity to me so I’m the only gurl he has ever been with I get I have to show him thing n etc. but when I ask him if he wants to he says because of scaring from sugar bumps that I had in the past n because it is to discolored down there nothing about smell nothing about anything else idk how to deal with this it’s tearing me apart on the inside to the point I feel so embarrassed to even have sex and more but I’m so attracted to him I can’t help my self but when I remeber I’m like well he’s perfect in every way how come there’s flaws in me 😞
