Yeah. My advice would be to work on your acceptance of the fact you have a thing for BBM (big beautiful men!), and that it's perfectly normal!

Overhearing your sister saying those things wont help, as you are being judged - however, you are being judged on something that she clearly doesn't understand. In fact, I do feel a major proportion of society remain small minded about the world of fetishes, until they eventually discover the world for themselves of course!

what turns you on, turns you on. Ive just recently come to terms with a strange one of mine too, with a little difficulty. Society is harsh these days, and generally taboo remains taboo as people are afraid to step out of the norm (particularly when it comes to sexual urges - shock! I said it!!)

Work on that acceptance, if you are afraid to be judged, then only open up to the people you trust with your heart or whoever you get involved with relationship wise. You'll get there. Look out for comminities that have the same tastes as you - maybe then you'll actually see how normal it really is.

Enjoy! x
