Most Helpful Guy
Most Helpful Girl
Sometimes I honestly think some guys are just after nudes and fap material.
It's best not to send those things to those guys unless you want to.
If they argue how will they know you are real, well you tell them to set up a date and meet in person. OR video chat on Skype of something. Those are ways you can prove it to them without having to take off your clothes.
I think it's really disrespectful for a guy to say that you have to prove your real by sending nudes or bikini shots. Any guy who ask those questions should definitely cause you to be more cautious.
If they are truly scared, afraid, terrified even of meeting a girl who isn't their definition of attractive, then they need to just move on. Why is it so bad to go out for a coffee with someone to see if there is chemistry? Has dating really gotten this bad that the guy can't spare an hour or so of his time? If they meet the girl and she isn't attractive, oh well on to the next person! Seriously, it's that easy lol
I can see a request asking for a full body pic of you fully clothed, that's reasonable. But asking for nudes is not okay.
