Would you ask a girl to consent to sex with an app?

Both the article and the thread so far seem to miss a crucial point: consent can be withdrawn.

"I changed my mind" effectively renders this "contract" null and void. The only (near) 100% sure-fire way to avoid a false rape allegation is to videotape the whole thing. Good luck with that, gentlemen.

Maybe when you go to a fraternity party you should sign a contract that forgoes your right to sue if you get injured in a fall, get raped, or otherwise get hurt.

I told my son that it isn't even safe to go in a frat house to deliver a pizza and it should say "abandon all hope all ye who enter here" over the door.

I sure would. Can prevent some problems (think about Julian Assange for example).

I hope they have good security and nobody steal the database.
