give head but won’t get head

this guy i mess with won’t give me head because he’s “scared of stds” but i give him head and we’ve also had sex without protection? i don’t wanna guilt him into doing it but is it not immature that he doesn’t give but he receives from me even though he knows i hate doing it

update now he said he’s just not comfortable and “is it really that big of a deal”... I cant believe i went through such a fucking traumatizing experience for him to think giving a girl head is gross
