Very unclear. You messed up, Girls has asked you to tickle her, she afraid of you because it tickles so much, and the boyfriend who doesn't like anyone else to touch her. How do these random elements combine to the problem that you messed up somehow?
There was one gal I tickled a few times who got a rush out of it, like parachuting, jumping out of a perfectly good working plane just for the exhilaration of dropping an incredible distance. Tickling is non sexual for her, and boy can she trash around like she's really having a hard time with it, but she's loving every second of it. Never found out if she has a boyfriend or not. Would it matter? How about elaborating some?
