I had met this lady off OKCupid like two or three months after my lady and I broke up. We got drinks the first night and had a really cool conversation about GoT and cartoons and shit. She wasn't super cute, and was 4 years older than me, but it wasn't bugging me. We made out in her car like teenagers and she said "I promised myself I wouldn't fuck you on the first date, but I'm off work tomorrow and you should come over." Being a person who possesses a penis, I agreed. Fast forward to the next day, I'm in her room, she's psyched on me and I'm psyched on sex. We go at it for a while, and I tell her (truthfully), "it's always super hard for me to finish with a condom, so this might not work out," to which she replies "well just take it off then!" At first I am psyched, but then I ask the fateful question: "are you sure?" "Oh yeah, it's totally fine, I have a couple plan B pills in my nightstand just in case."
"Oh jesus," I think, "she just keeps those on deck!? Is this a regular occurrence?"
But, again as an owner of a penis, I whipped it off and went back at it, and ended up blasting on her face. (Later on I convinced myself I had AIDS and got tested, clean thankfully). We boned like 5 more times over the next few weeks and then I stopped returning her texts.
Not the best story, but a little awkward and very scary after the fact.
