request for sociologists

i’minterested in the culture of hooking up on tour. since i’ve never been able to accomplish a hookup at any time, tour or not, i may find the whole thing more mysterious and exotic than most people.

but i’m curious because of the cliche/expectation that going on tour will involve romantic interludes or various sorts (whether one night stands, casual hookups or the prospect of long term romance, and whether it might just be some face kissing, heavy petting or full blown sexy times). because that expectation exists, and persists, and i’ve been touring for 13 years without seeing much of this happen. i mean, yes, i toured with my partner for 10 years, but it was so uncommon with my other bandmates as to be statistically nil. so it seems like this ubiquitous thing, but then in my experience tour involves pretty much none of this.

what i want to know is, do most partnered people struggle staying faithful on tour? do a lot of them cheat? make/have arrangements with their partners?  do most single people hook up on tour? do they hook up at home? is there a difference in frequency/intensity because of knowing you are far from home?
is this pervasive stereotype of tour being in some way a sexual temptation heavy culture just about big bands? just about non-punk bands? because i’m not talking about groupie culture, which from what i’ve experienced is not a reality for the punk scenes i’ve been involved in. is it just about meeting so many new people in a short period of time? is it about anything?  
yeah, i don’t know. could some sociologist get on this for me? maybe i should just make a questionnaire to send out to musicians?
