For a long time I thought something similar, that guys that went to strip clubs were sad, desperate, and dirty old men. So figured def. not for me, and also couldn't see why I would just give away my hard earned dollars to girls that just "act" like they like you or are interested in you in order to get more money out of you.
So for years friends would try to get me to go but I wouldn't. Then a couple of years ago I finally got talked into going with some friends after work one Friday night...
And it was a great time, sure the loser, desperate, and dirty old men are there but with friends and drinking it is a good time not to mention some of those girls can really dance as well have impressive pole tricks. One of the girls picked up my friends beer bottle between her butt checks (empty bottle) and the girls were fun letting us slap them on the ass as well joking with us. Great time
I don't spend all that much, places like the Pink Pony's and Oasis you really don't have to spend any more than the entrance fee if you don't drink anything as well don't get any lap dances.
So all in all, as long as you know those girls are just working, and don't go all that often to blow your cash... I see it as good entertainment with friends and nice to see often good looking girls showing what their momma's gave them
