Being old fashioned dating
Hell, my most recent date started talking about a porn festival he recently attended, and the "sexual revolution".
I've been on a variety of apps during this time (Ok Cupid, POF, bumble, the league and now tinder) and the only consensus I have in all of my experience is that a large majority of men are very sexually forward as soon as we exchange numbers.
It’s not a requirement to ask before kissing me, but it is a total plus. I really love when guys take the time to do the same thing.
