<human>: Can you give me the gist of the text in a nutshell?

I don't think there's that much to explain, but I'll give more details anyway. I've had this fwb relationship for some time and he's proven himself to be amazing in every way that I don't think I can find anyone else as perfectly matched in terms of sex and fetishes. Most of the time he would come over to my place, we fuck, then he leaves. Occasionally I'd tag along to hang out with his friends for a drink and I get along with them too. They don't know our actual status so they assume we're boyfriend and girlfriend.

Last week I started chatting up another guy and we just met yesterday for the first time at 3 AM for a drink (yes that does sound dangerous and careless I'm sorry mum and dad) and we had a great time together, driving around aimlessly till 530 AM and stayed at my place sharing music tastes (which turn out to be similar) by taking turns watching youtube music videos until he left in the morning around 8 AM. He's a sweet guy and seems to have taken a liking to me already.

Now, I'm in a difficult position. As selfish as it sounds, I don't want to give up the sex I'm having with the fwb until he goes overseas to continue his studies this year. I personally don't want to disclose the fwb relationship to the newer guy but if this ends up as a serious relationship I probably should tell him very early on for the sake of honesty and clear communication. 

What would you guys here advise that I do? Thanks for any input in advance.
<bot>: Might start dating a guy but I've been seeing another guy who's a sex friend. Trying to decide if I should explain myself to him about the fwb.
