I have always used tickling to flirt, always have, and probably always will. I usually make sure the other girl and I have had a couple of conversations first though. If I think the tickling wouldn't upset them, I eventually go for it.
Its the best!
TIckling to flirt? Oh man.....absolutely.....couldn't begin to tell you how often I relied on tickling to flirt with my female friends/a girl I had special interest in.....nicer yet is they all responded rather favorably!! Some even more so than others....
Sometimes I flirt with it, sometimes I just tickle..I lots of my tickle pokes with friends and ladies I work with come from my tickle demon within.. Cause I know i've tickle people that i normally wouldn't flirt with, I just couldn't help it sometimes.. And its caused misleading emotions.. oops
When I was 20 I tickled my friends mothers feet as she laid on the couch. I suppose it was a way of flirting, maybe to take it to that level where it would be a spring board on to something more physical. She laughed her head off but the second time I did it she seemed annoyed amidst the laughter. I was absolutely incredible though. A friends mom? How forbidden!
