As for guys, there are only 2 types of guys who use online dating, whether it be Tinder, POF eHarmony etc etc
#1: The guy trying to get some pussy. Once he has got it in, you are probably no use you him unless you plan on putting out again (without commitment of course). This makes up 95% of male users. He could be young and on his V's or old and trying to recapture his youth but girls don't be fooled by his profile which may say differently. Rest assured he doesn't want to "spoil you" and he isn't into "bushwalking" or "the arts".
#2: The forever alone white knight. Deep down he is the same as guy #1 but he believes the way to get girls is to give them gifts and shower them in compliments in the hope that they will one day want to "settle down with a nice guy". Sex isn't even a priority right now and #2 would settle to just have some semi-positive attention from the opposite sex.
