So if you're on a date with a girl for the first time and you have to take a dump, it's not an issue?
If you gotta drop a deuce, drop one.
If you're in your mid-20s, early 30s.... good looking, in shape, good career, disease free... you pretty much call the shots when it comes to girls. Eat healthy foods on the date and in the 2 hours before it, drop a deuce right before you leave, and you'll be fine.
Obviously, don't load up on tacoes then use her bathroom (adjacent to bedroom) for 30 minutes while she waits to get laid. Plan it out, bring her to your house so you can park her in front of the tv and "go check on the cat's dish and check your voicemails" then disappear and crap away!
