Is it normal to find a stripper up for casual sex.

I've been going to this strip club for a while and its a bit of a dive. A small little repurposed bar with 5s and 8s on stage for a lucky night. The cute ones rarely give dances and if they do its a pretty close contact affair with hands on at the girls discretion. Bouncers and security are nowhere to be found, and the only male on staff is the 80something owner.

In the time I've been there ive found two girls who seem to go a little wild but only during lapdances. Its a topless bar yet I've had hands in my pants and bare crotch in my face without a word about extras or even a handsome tip though I have tipped them afterwards. I tend to spend about 60$ a dancer for 3 songs with 20$ tip if I liked it and i ask before trying anything adventurous but usually by song 2 they slip the bikini too far down and my hands are free to roam. The girls know my name and habits by now and its the type of bar when the girls sits next to regulars its usually to start a long conversation and not to stick a dollar in her bra.

is it normal to try to have sex(protected of course)with a stripper if she seems willing and doesn't throw down a price tag for what are normally extras?
