Was chatting up this moderately cute girl that messaged me on Tinder

Blah blah I start escalating to sexual stuff and she's flirting along but ends up saying she doesn't do blowjobs. I replied with "okay" which she loved because she thought it meant I didn't care.

So I end up nexting her, lol sure she's pissed. Was that the way to go? Seemed like a waste of time to me
