<human>: I became friends with this guy in the spring at the university we attend, both students in the same major. About a month into our friendship we got drunk on some red wine and slept together. After that, we started hooking up regularly on the weekends. 

At first I enjoyed our Friends with Benefits perks of no commitment and great sex, but the more we hang out together the more I've grown to like him than more than just a friend. However, I am too nervous to admit my feelings to him, because I don't want to ruin our friendship or our great sex. 

Being friends with benefits has been hard to read any "signs" because I don't know if he's just being a good friend or more than that. For example, he bought me brunch one morning after we hooked up, and I wasn't sure if to take it as a friendly gesture or as something more. And let's face it, brunch might be the most couple-y thing ever. 

Also, we can't hang out a lot because we both work 8-5 corporate jobs and he has to spend some weekends studying for the CPA exam. Also, he's not much of a texter so it's not unusual for us to text infrequently. Despite this, we have a good friendship and a lot of similar interests and can talk for hours when we are together.

I got out of a 3 year relationship in the spring and wasn't looking for anything serious, and when this guy and I first started hooking up he didn't want to tell anyone to help keep me from tarnishing my reputation in a small elite college program (I'm one of the only girls).

My question is, how do I start this conversation about my feelings for him? Do you think it would ruin what we have now?

Condense the text into a few key points
<bot>: Not sure if I should pursue having a more serious relationship with my friend with benefits with the risk of ruining sex and friendship and I am not sure if there are any "signs" pointing to him wanting more.
