Roleplaying adult/child scenarios sexually is controversial as it can arouse concern in many people's minds, due to the sensitive nature of its subject matter. However as with other sexual fantasy it is not, by itself, necessarily a problem, and can be for some, a healthy or healing outlet, and for others like any fantasy an exploration of different roles and feelings.

I did a quick google search on "age play" and "age play BDSM" and I came up with those links. I've never personally engaged in age play, so I don't know that much about it. But I decided to try and come up with some things to help you. Hopefully some others on here who may have engaged in it will give their two cents. I hope this helps!
