IMHO, I don't know (or hear of) any gay guys using vibrators. They seem to be thought of more as a girls accessory even amongst the gay community, but I may be wrong.

The kinky experimentation with E&E is fun, but it is the romantic passion that is spurred just by the scent of biscuits that is kinda sweet. Hell, not that they need any prompting for sex! LOL
