What to do ?

So my boyfriend and i been together for 6 months and i have been having the hardest time in the bedroom with him normally I'm able to just cut loose and do all kinds of dirty things to the person that I'm with a little background I used to be a dancer at one of the strip clubs near to my house and after I stopped dancing I met my boyfriend and ever since I stopped dancing I can not be extremely dirty in the bedroom I cannot do it and I don't understand why when I was dancing I never really had to do anything dirty with the men that were at the strip club but you know we did do lap dances and other girls did other things hence why they made more money than I did but that's besides the point I don't know why I can't cut loose and be that open with the person that I'm with now when i used to have no issues in past relationships.
