<human>: So I[24/f] have been dating two guys [both 30 M], let's call a guy that I like Sam, and the other guy Tim. 

I met both guys at similar time, only 3 weeks ago. I slept with both of them, but since I slept with Sam I haven't seen or slept with Tim, and I want to focus on Sam (although we never talked about exclusivity). Sam and I chat and texts on daily basis, whereas with Tim, we never text and he invites me over for movies and sex only.

I slept with Tim on a first date first of all. Met at a bar, he asked me out on a date, slept at his place that night.

With Sam, we slept together on a 3rd time that we saw each other. I came over to his place to make out, we actually ended up laughing for 4 hours straight and it was the greatest time ever (we did end up having sex).

I connect to Sam better, he's so much nicer, he brought bottles of juice when I was sick after the work.

So the question is, should I end things with the other guy? I honestly want to focus on Sam, but I know I haven't known them for a while, should I give both a chance? I don't feel comfortable dating two guys at a time though...

Also, how should I end things with Tim? Should I meet up with TIm and tell him or should I text him or call?

Please help!
