Hey my girlfriend is 21 years old and it seems like when ever she is over her 2 best friends house and she takes a shower, she takes it with both of them.
I brought it up to her that I think thats weird and its something preteens do, assured me that she wasn't a lesbian or what ever and she does it to cut time down in half for work since she has to get up at 6am.
Find it strange as hell, don't like it at all.
