The timing of sexual flirting – of what you say or write to a woman you are interested in is just as important of what you are saying. Look at the actual Bumble messages below. This is the type of sensual flirting that could really heat things up after the two of them actually met in person, felt mutual strong attraction, and had at least some physical contact. On the other hand, talking this way to the girl the guy never met makes him come across as nothing but creepy. Even being mildly sexual with a total stranger, will surely get him blocked / deleted by the girl he is talking to, who otherwise might have responded quite positive to him, if he only waited to get to know her a little better before talking to her this way. The same can be told about hook up for life and marriage comments. This is coming on way, way too strong, and way, way to early.
With flirting, I think it’s best to start really really small and work your way up if the other person responds well. That’s exactly what flirting is. You only go an inch at a time, so if you ever go too far, it’s not a big embarassment.
