<human>: Using a throwaway because some family and friends know my reddit username. I cheated on my boyfriend with a gut I met on Tinder about one week ago. Since meeting him, we have had sex twice. I have no romantic interest in him, but the sex was amazing. 

I have an interesting relationship with my boyfriend. We met online and he only lives about an hour away (and he commutes to where I live, and where he works, 5 days a week). We have only seen one another a handful of times but when we do, it's usually for a few days. It took him almost a year into our relationship to kiss me and we have still yet to say "I love you" to each other. I don't even think I love him yet, but I do strongly care for him. We have only had sex two or three times and it wasn't even that great, as he is fairly small. The sex I had with random Tinder guy was amazing compared to that. 

I'm just conflicted and don't know what to do. Do I tell him? Keep it a secret? Break up with him? I'm new to relationships and have only had one abusive one before this, so a "normal" relationship is something I've never experienced.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Cheated on my boyfriend of 2 years, that I don't love yet, with a guy I met on Tinder.
