My college friend of 3 years is also my friend with benefits currently. We have a little bit of a history, but only started having continuous sexual relations about 3 months ago. We agreed to "keep it casual" at the beginning, but it seems that has changed. I believe now we both may have unspoken feelings for each other. But we share many mutual friends, and might be too late into college to start a relationship, so I might be risking too much by bringing up feelings in a relationship that is already satisfying. We both get what we want out of our friendship and our sex, but intimacy may cause us to want more emotionally over time. This might blow over and I'll be thankful I didn't say anything, it might be something that happens eventually without me bringing it up, or I could try to address it now.
