getting laid with online dating ?
I would guess the majority are just looking for random sexual hookups. Some sort of eHarmony matching for sexual partners would probably be an overwhelming success.
for sex the problem is the same as in "real" life, women can choose so i doubt its just hooking up over the internets to get laid...
if guess its 10 to 1 or worse men to women wanting to get laid...
and that 1/10 is not jessica alba.
Given any sort of relationship definition, I would guess that is never far off 1:1 for women and men interested.
And not all men are interested in finding Jessica Alba...she is obviously attractive but that is only a piece of the puzzle :)
What I was trying to say was the number of women in general who participate in something like one night stands or a purely sexual relationship MUST be closer to 1:1 than 10:1 or 100:1.
Hence, there is great opportunity in putting together both sides of the equation, online sites by your numbers need to somehow draw the attention of women who they are clearly neglecting to serve well.
