The best birth control ever

Putting two suspicious sounding chemicals in a part of my body for a prolonged amount of time (10 years wut) doesn't sound like something I want to be doing. A quick search shows that dimethyl sulfoxide is mildly toxic, and styrene is potentially carcinogenic.
:l

To be fair, unless you're a member of the industry, it's likely that almost any substance is going to be "suspicious sounding".

I can't say anything to the extent of dimethyl sulfoxide's toxicity, but, in my mind, the world is too big a place to be worried about "potential carcinogenics".
Mostly because almost fucking everything is a confirmed carcinogenic or a "probable" carcinogenic.
Examples:
Alcoholic beverage consumption
Environmental tobacco smoke
Solar radiation
Wood dust
Art glass, glass containers, and press ware (manufacture of)
Engine exhaust, diesel
Frying, emissions from high-temperature
Hairdresser or barber (workplace exposure as)

How about this solution; stop being lazy, and stop giving people excuses to be lazy.
It doesn't take a lumberjack's worth of effort to, god forbid, remember AND use a condom/take a pill. e_e

Yeah, screw those women too lazy to take birth control pills! Clearly, all those women who don't want to take the pill are just not willing to put in the work!

Good thing you didn't make yourself sound like a male ignorant of women's issues right there.

This has to be reversible though because I am 20 and if I decide that I want babies when I'm 25-28 and it turns out I can't until I'm 30+ I'll be pissed.
In terms of casual sex though, condoms are always #1.

I'd mostly be hesitant about recommending it mostly because the study is so relatively new.
Then again, I'm always paranoid about potential long-term effects of chemicals.
