People change their appearance and function in small and large degrees all the time and throughout all known history.

Sometimes temporary, like wearing clothes at all in many climates for decoration, to enhance some attributes and hide others, to wear make-up, to wear jewelry or body paint, to wear masks in religious ritual to 'become' a sacred animal spirit or god.

Sometimes permanant like tattoos, ear piercing, facelifts, cranio-facial reconstruction for those born with a deformed face and skull, hip replacements, breast enlargements and reductions, body piercing, lobe stretching, lip stretching through to the full face tattoos of the Maori and the full body tattoos designed to resemble reptile scales of the totem of a south east asian tribes (don't recall the name, sorry) to the extreme, like the practice of cutting the penis of males almost completely in half as part of the intiation into manhood of one Aboriginal tribe (to make it look like the twin-penis of their totemic ancestor-animal) which is but one of the many genital-surgeries and other body modifications of traditional peoples that have survived from ancient times to the present day.

Compared to all the many variations of human behaviour yours is mild and harmless. Your presence is just exposing us to difference and that does no long term harm and a lot of good just like meeting and getting to know someone from a different race or culture or religion does.

If people think your turn-ons are creepy they have not begun to explore the wide variations of human sexuality through the ages and still existing (like using bee stings or vomit for sexual pleasure or once a year having sex with the mud with every other adult male in the tribe right alongside you to fertilise the mother earth literally!) or the wide varieties of cultural practices through history and still existing today.

Too often the western world sterilises and ignores much of the worlds cultures giving a false impression of what is 'normal'.

We need exposure to variety and to difference so we can judge people on the rightness or wrongness of their actions, not on the sameness or diffference of them!

And as long as it only involves adult humans without cognitive impairment giving fully informed consent then a sexual practise, no matter how uncommon, is right and not wrong.

Making you Sherry far more right in your sexual behaviour than the average person who has a one-night stand with someone who is drunk (cognitively impaired). Yours is less common but right, theirs is very common and yet wrong!
