advice about oral

so yesterday i gave my boyfriend oral for the second time. he didn’t finish in my mouth my first time he just let me know and gently moved my head away, yesterday he asked if he could do it in my mouth and i said yes to give it a try, but i discovered i don’t really like the taste of it... i swallowed anyway but it wasn’t very pleasant. should i tell him? if so, how would i go about saying it?

also, i know this is probably just me overthinking because i’m kind of paranoid when it comes to things like this but should i be worried about getting an sti or anything from that? i’m pretty sure he’s clean, i think he’d tell me if there was anything like that. let me know what you think and how i would go about talking about this stuff with him

(^ i know i probably sound dumb being worried about sti after already performing the act but 😭 i just need some friendly advice please)
