...What should I do?!?

Hey im a "gay" guy 18 and ive never had a bf or anything... But I want one like really bad(like literally been sad for like 3months)... But the thing is... I dont know if I can handle it, because I like, get bored of people kinda fast like I love the people I talk to I just cant stand being with for too long. Im just like when they are talking i sudenly say.. Shut up and then I leave (not trying to be rude... they know im kinda like this so they dont get pissed)and go to someone else... so that might be a prob. And I enjoy my life without sharing it so much I dont have like super BFFs just cause when we start to share things ( like being too much time with, talking serious crap and stuff like that) just freaks me and stresses me out and i get annoying ( though I want a BFF too lol) but when im alone like for long Im like damn I nee to be withsomeone and I dont like to hav my apl on a group of friends I like to be friends with everyone so im alone sometimes cause i dont got my pal ( get what i mean?!). And at those moments is when im like that .. Amn i need someone but cuz how i am im not really sure able to handle it but it's not like i dont njoy not being alone.... Any tips or something i could do/use pls?!
