Drunkenly kissed my coworker who's twice my age. Don't know what to now.

Just a little context, I'm in my 20s, he's in his 40s and we both work in the same place but not for the same reason.

Yesterday we had a company party, it's a big thing every year so I was excited to come, but I definitely had too many drinks. After a bit he came to dance and talk with me, he kept flirting, but it's always the case so I didn't mind or care. It kind of escalated when he kept his hand on me a lot. I left to go to the bathroom and he came with me, idk what I said exactly but he responded with "I should get a kiss for that" and I did kiss him. I don't regret it, but it's not at all what I would do if I was sober. Now that I am, i have no idea what to do. I vaguely remember him telling me he would like a sexual relationship with me, I didn't say no. But I literally have no experience in this, I had one ex with who I did my first time with and that's it.

Now I know it's gonna be a mess, and I put myself in this situation, so I have to take responsibility but it's kind of scaring me.
