After long searching I have found that Trojan Magnums fit me "best". All other condems are way to small and roll back up when i put them on (I am thick to the point where my girlfriend can barely have sex with me, and I am not her first). However, When I wear Trojan Magnums, they are tight to the point where the circulation of my penis is cut off eg half of me is rock hard and the other half is flaccid, (looks hilarious feels crappy). Is their any condem that could fit me better? Its not an issue with length, its an issue with girth. All help apprciated.
