You may also want to buy a massager style vibrator and complain of back problems. "Ugh, my back is killing me, I'm going to go deal with that"

I have friends in dorms who swear by that method. However, if you're dead set on a rabbit. this looks good.and not too pricey. I also recommend Ina by LELO, but they are expensive and students are generally not in a position to be spending tons of money. Though if you can bring yourself to save up, they're fantastic, rechargeable (which saves you loads on batteries) and last forever, which cheaper rabbits don't tend to.

Also please make sure if you use a porous toy you pop a condom on it before use, many cheaper materials either hold bacteria or emit nasty chemicals (and sometimes both).

If you can, a silicone toy is your best bet.

Another great silicone rabbit is the Tango by Fun Factory or if you want something silicone but a bit cheaper the Fonzie by Feelztoys might suit.
