You hit the Nail well and truly sir.
I've had one person who actually replies with a decent come back, I think I'm just going to not send messages to those who can't be bothered to think of something responsive.
Personally speaking I find it is me doing all the leg work whilst the females just seem to sit there basking in the attention they are receiving. I think males seriously out-number females and I think a lot of girls on there have no intention other than to make themselves feel attractive/wanted.
