<human>: Can you provide a brief rundown of the text in within 3 sentences?

Ayiyi. My coworker got a flat near me recently that he shares with another coworker of ours. Last night he invited me over to see their place and have some drinks where we proceeded to drink beer that turned to liquor that turned to having sex with my coworker. So, I like this guy and was excited when he moved near me because we get on well and had pretty instant chemistry. I didn't expect much from last night but that's what happened and now I'm feeling weird from two points. On the one side I feel like I made a mistake by having sex with someone I was interested in and am feeling like I slotted myself in the easy lay role. On the other side, I had sex with a coworker and his roommate/my other coworker knows about it. Blah. Luckily he works remotely so the only time we see each other is outside of work or at work events. 

How do I handle this? Anyone have experience with that? Halp.
<bot>: fucked my coworker and feel like I just slotted myself as a slut when I was kind of into this guy and curious to see where it went. Also worried about the whole professional side of it.
