I have annoying roommates who are the type of guys who would try to get a pic of you jacking off and post it on their facebook page. End of story. Can't really PE in the shower cause they'll suspect something. So I am gonna start doing everything in the privacy of my room, hopefully. But when i tried a few oils they are really hard to wash off without a shower. Do you recommend anything that I could use and clean off with a washcloth or something of the sort? Something that I could get enough off of to survive till my morning shower?
