Slept with a coworker, AIBU to ask him if he wants it to continue or keep it as a one off?

[Nothingx]

Bit of background.

First hooked up with this co-worker when we went out as a small group of colleagues day drinking. We were getting with each other all day/night (unexpectedly) nothing else happened.

We then ended up having sex a couple of weeks later after some work drinks (the whole night was very flirty). We don't message or anything, things have been fine at work. The odd flirty comment and general look.

AIBU to ask him if he wants this to continue or not? I don't want to continue being a bit flirty and forward with him if he isn't in the same mindset. I don't want to look stupid/eager etc.

I don't want a relationship out of this, its purely a bit fun. Thoughts?

Honestly? If he wants to continue, he'll let you know. Leave the ball in his court.

I did this OP.... Months of flirting, ended up sleeping together, then had a chat about whether it was a one off or not and we decided it was fun so we'd carry on as fwb....6 years, a child and a house later we're still having fun lol. Well mostly. Except when he decides to discuss the merits of the A1 over the M6 with me for over 20 minutes 🤣

I understand leaving the ball in his court but, I don't want to come across as too forward if this isn't going to continue, even though he does come across as flirty (when it's the two of us mainly as we don't want anyone in the office finding out) I will feel like a bit of an idiot.

Why would you be too forward? You slept together already there is no too forward. Do you mean too desperate or eager? Do you mean clingy?
If you cool off flirting and become cold how do you think he will take this? He will think you've changed your mind and he will back off too.
I would match his energy in flirting and let him initiate. You don't need to go above or freeze him out. Follow his lead ... or ask him if he wants to be your fwb?

Yeah maybe too eager is the right word. I think we are at the stage wheres there's alot of underlying sexual tension, so it feels at a bit of a weird stage. I'm not sure how he would take it if I cooled it off.

I just didn't know if it would be better to have a conversation of 'do you want to continue having fun or not?' maybe not in those words.

I agree with PP. Match his energy. If he wants to continue he'll let you know. Personally I wouldn't ask because I think it's usually fairly obvious.

You've slept with the guy and are now worried about being a bit foward?

That ship has already sailed. Just have the conversation instead of behaving like teenagers.
