आप can't really stop a person from being interested in you, sadly. Though, a lot of straight guys probably would want to be in your position. I guess if they won't lay off and आप keep assertively state you're not interested, आप might either want to block them, ignore them, या be incredibly annoying to the point they don't even want to talk to you. To be honest, I would have और fun trying to be annoying *innocent smile*.
Just turn them down. Do it as many times as आप need to.
I might know how आप feel, a little. Whenever I use an आइकन of Brandon फूल on other websites, I get multiple girls giving me their phone number and asking me out. I can't even tell आप how many times I've had to explain to them that I'm not Brandon फूल and that I'm not even a guy.
Wow...to think someone would admit they're gay on a global website. You're really ब्रेव dude. Here's my advice, tell those girls you're gay and not at all interested in them, and be firm with it. After doing that, pray they go away, because certain girls can be clingy for reasons that can only be comprehended द्वारा their types.
I actually was somewhat in your position a few months ago. Some girls were being overly inappropriate and it bothered me. This one time she asked me how big was my dick. To which I was bothered. The only difference between आप and I is that I'm straight. Honestly I would tell them off. But आप seem like a guy who wouldn't do that so I'll suggest आप block them from your प्रोफ़ाइल wall,Im and meebo and unfan them. MAYBE they'll get the hint. If they don't, ask someone to talk to them for you.
Hmmm... Well, from already पढ़ना all the जवाब and टिप्पणियाँ on this question, I don't really know what to say because everybody took my answers... and from the टिप्पणियाँ where आप note additional details, I say WOW, those chicks are crazy! And all these girls...? How many of those girls are there?
Also... There is a continuation to this answer but I think it might be a bad idea for me to make it public (no, I don't want to say that I'm also gay या anything like that, in case anyone's wondering)... so I'll send आप (hetaliaitaly) a message about it.
In the meanwhile... remember, my reaction to those chicks is this:
Ok, I know this answer is different from the rest. Here goes, first I would thank them for the complement, but tell them that आप are not interested. That way आप are not answering them as a gay guy, but as a caring person. If the problem persist या gets worse, आप can be और direct या unfan them. I get the feeling from your सवाल that आप are not out to hurt these gals. Start out gentle and go from there. That's my opinion.
