Tell him you have a chronic reaction to condom latex and that it makes your skin dry. And that because of all of the action you are getting, you need to massage this oil into your dick real slow. Also to make sure it doesn’t wrinkle, you have to stretch it out. You get to be a stud 2 days on, 1 day off and get to do the newbie routine if that is the thing you wanna do. Whatever.
Why tell the truth when an elaborate lie that may backfire is so much easier?
Alternatively put a tie on the door knob when he is out… I believe that is the international symbol of ‘I’m getting lucky… stay the fuck outta here’ or a sock, which is similar but means your knocking one off the wrist. 2 horny college guys??? Sheesh, don’t be so prudish… you might not need to tell him, but men love putting their hands on their cocks. I betcha ol’ Poindexter there is wishing you would get lost for a couple of hours so he could burp the worm finally. ;)
I am imagining your roomie right now typing out on a forum board somewhere, ‘Little does he know, whilst bdragon is gaming on his laptop at the moment, I get to relax that he isn’t going to look furtively at me and when he thinks I am not looking, he puts his hand on his wiener. I haven’t had a decent moments sleep since I got here… every time I hear a noise at night, I wake up to make sure it isn’t him climbing into my bed.’ Needless to say, I find this situation hilarious. I am obviously offering no deep insights or real advice but hey, if we cant laugh about shit, what can we laugh about? :)
