From onlulu.com's FAQ:
"Lulu Dude is a separate app we created for the boys because we do not let them into the original Lulu.
Guys don’t see what the girls see. We let them select their relationship status and profile picture and we encourage them to get their “fan base” to review them.
Lulu Dude is also a place for guys to get self-improvement tips. Think of Lulu Dude as Cosmo for guys."
