Gaining

I somtimes like to make fattening concoctions, such as peanutbutter mixed with butter and sugar, and eat them to help me gain weight, and sometimes I get sexually aroused just thinking about how fattening the food I'm about to eat is, and I was wondering if anyone else has similar expiriences with stuff like this.

I kind of understand what you mean. When I like to stuff myself even the thought of buying tons of fattening foods at once is arousing.
