Condoms. That's it. We use plan B if the condom breaks or comes off, but we've had that happen, like, once in five years.
I was on depo for a few months, and that was all we used then, but it killed my sex drive, like, literally ZERO sex drive, and I've been off it since JULY, and it's JUST now starting to come back to normal.
I'm NOT wanting kids, ever, so as soon as we're 25 (recommended age for a male neuter, lawl) Steven is getting a vascectomy.
