Just the slightest thought? Damn, that is a dangerous drug...they should also include a list of places one should not go to...
1) like don't take it before going swimming at a public pool or beach. You would be arrested for being a perv.
2) don't take it before going for a 2 hours massage. Would be painful when the girl walks on your back.
3) don't take it before playing any contact, team sports where there are cheerleaders/female fans nearby. The guys will kill you either for running too slowly or bumping them with your dick.
