When is a good time to confess feelings for a friends with benefits? What was your experience like?

So I met my coworker 4 months ago, he left our job 2 months ago and ever since then we’ve seen each other once a week and talk everyday. We go out on walks and we’ve been to the arcade. We never officially stated what we’re doing but I’m assuming we both are friends with benefits. Meaning we’re friends and have sex :) He’s so sweet and I like him a lot but I just got out of a bad relationship 3 months ago and I’m not sure if I am ready for a relationship. He has also stated that he doesn’t fall for people like that. But we talk everyday, see each other a lot. He calls me gorgeous and we’re always saying to each other how thankful we are of each other’s existence and how we vibe well. Our kisses are literally melty and I feel his energy on me every time we stop kissing. He sometimes explains how he gets really nervous around me bc I’m always offering head and he says I’m always intense with sexual stuff that he feels like “he doesn’t deserve me”. Point of this is , I can feeeel a connection and I think he’s not admitting his own feeling to himself but I could be wrong. I also like to take my time with love and things like this so I’m debating on continuing and giving us more time to know each other. But I really want to tell him how I feel, I just don’t want to scare him off or ruin what could potentially just be if I let things flow. Idunno, I’m in a pickle. I wouldn’t mind not saying anything and just seeing how we flow but I don't know if that’s the “wrong” thing to do. Help? Sorry if I seem like a wimp for not knowing what to do ! I just get flustered and I should probably woman up and tell him my feels but I hope you understand why I’m doubting doing that. Thanks for the advise to those who comment !
