Ok so I don't go to church often, but my family does and they always joke around about me going to bible study so I can pick up a "Good guy".. I'll joke around and see a pastors son on tv and be like Dzamn I'll definitely go to his church 😂 (totally lustful) and my sisters will laugh and jokingly call me a sinner. It's all really just comedy my family's kinda like that. A few days back I commented on a video of these dads b4 and after they shaved their beard and how the babies would cry because they didn't recognize them, anyway my comment was a comment on another user saying this specific dad (who was singing a Christian nursery rhymes type song) ended up being SUPER HOT after shaving his beard and shocked quite a few people.  Jokingly I commented "what church does he go to?😂😂😂 lmfao" appearently someone didn't think it was appropriate to "pick up someone" at a church.. 
Which made me think of these questions, is it wrong to to "pick up" someone at church? Wouldn't you want someone with similar interest? like that saying "you don't meet your wife/husband at a strip club". 
All my sisters met their husbands at church.. so I'm assuming it's not wrong to hit on someone at church 
SIDE NOTE: I'm already in a relationship, so I'm not looking nor would I go to church just to get a bf I'm not an idiot,its just an ongoing joke I use to say a "Christian man" is attractive to me. Also by "hit on" I mean "asking out" .. I may have worded that incorrectly 😬😬
