Is it normal if i don't know how to flirt on purpose?

People say I'm a flirt and sometimes I'll catch myself doing it like "oh sh*t, haha oops? didn't mean to give you the wrong idea", what can I say I have a natural, flirtatious personality. But when it comes to actually trying to flirt like if the guy is talking to me about sex, asking me questions what I would do, you know I should flirt back but I just don't know how, lol. I feel awkward like "uhh shouldn't we be doing the actual thing rather than talking about it cause this is kinda awkward". I'll laugh and not take it seriously, its just funny to me. My sense of humor out weighs the flirting that's for sure, but the point is if its normal that I feel awkward when it comes to trying to flirt when I'm actually a flirtatious type of person, naturally. I also tend to get impatient and annoyed during flirting or "sexting" like ugh lets just do the damn thing already if you can't shut up already! whats the point?! I'll literally fall asleep on my phone or type like a zombie, yeah I get THAT bored flirting or whatever. Sheesh
