Perhaps the sites you are visiting, and your expectations are mns-matched. If you are looking for some way to fulfill 'these urges', perhaps a dating site where women may be looking for a more long term intellectual and emotional exchange is not the place.
There maybe sites more in line with your expectations, or perhaps you could explore more thoroughly what it is you are looking for.
Was there something in particular you were hoping for through using these sites, who were you hoping to attract?

Maybe by focusing your interests and wants you will have more luck finding someonecompatable.

Wishing you the very best.
