People change their sexual attractions ALL OF THE TIME. Used to really be into asians, now he likes redheads. Used to like bodybuilders, now she likes heroin-chic. The wife used to really do it for him, now he likes his secretary better. Used to be a leg man, now big boobs are all the does it for him. Used to like college girls, now MILFs turn him on. Used to like boys, now likes girls. Etc. Etc.
I don't care. They can do what they want. This thread is about the fact that people can change if they want to, not about making anyone do something they don't want to.
