not being awkward with kinks during sex?

i’m started dating this amazing guy who i have the best connection with- issue is that i have no clue how to actually call him daddy and ask him to slap my ass during sex 😬 we have such a passionate sex life which is great but since my biggest kink is BDSM, i feel like it’s so awkward to have us be crazy in bed with what we say and do when it’s just not us outside of sex at all
