Feminist "consent underwear" sparks debate

Video here. (Possibly NSFW since it shows images of women's racier-style underwear, so use discretion if at work/in a public place.)

Despite my problem with the presumptions underlying the idea behind "explicit consent", one good purpose these could serve is to let a guy know he's dealing with a girl who, if he doesn't get "explicit consent" from her, she might later accuse him of raping her.  At that point he can decide whether he wants to chance it with her or not, but to be fair, if he's already alone with her, she could still accuse him of raping her anyway and there'd be nothing he could do to disprove it.  Best not to be alone with her at all, really, unless she signs a form of some kind first and agrees to have their fooling-around session at least sound-recorded so the fact that she is consenting at every moment is documented.

I'd like to suggest the practical strategy of her just repeating the same phrase: "Yes, I consent, don't stop," until they're done with however far they're going to go, right up through the completion of actual *gasp* heterosexual intercourse.

I wonder, how do gay guys handle this?  Must they both get affirmative consent from each other the whole time?  And do lesbians not need to ask one another at all?

If two gay women start with each other, it poses a quandry.  They are both required to give affirmative consent but neither is required to elicit it.  Assuming sexual activity must start with an elicitation of consent but only from male students, then in essence such a rule stops lesbian students even from holding hands, maybe even looking too long at each other.  Or maybe they both just have to spontaneously start repeating "Yes, I consent, don't stop," until whenever they want to stop.

I thought I was glad not to be a college student before.  Now, I'm positively ecstatic!
