Yes, it has worked for me, but I have an exceptional disposition. I never sent it to a woman that didn't ask first, and only after some rapport.
1. Yes, some women look at them and get hot and bothered. Anytime i sent one out I never heard the end of it. They were even shared without my knowledge.
2. When thinking of hookups, it can play in your favor if you are already cool with a lady. I imagine its rarely a deal-sealer for brehs, but in my case, it has been.
3. Flirting and showing your parts is a thing now, as weird as it seems.
I don't get the sending it out to random chicks...thats strange. But when we already talking about fukking, its a nice way to put a stamp on it.
