What do I say to a guy who just texted me "I'm horny"?

[AnimeGirl_XD]

I met this guy a few months back at a friend's birthday and we hit it off. We've been texting each other since then, and it's been friendly. We had similar interests and stuff like that. We went out once, and that was for coffee but nothing happened. Since then, he's been texting me a lot and today he started with the "I'm horny" or other things like that. This was the first time he brought up something like this, and it made me uncomfortable. I have no idea what I should say to him. Any suggestions?

If you want to shut him down, then do as suggested below and send him "That's nice" xD. If you like him then send something funny back that so that he has a chance to get out of it and not look stupid after taking a chance. You could send something like "Oh my god, that must mean you're a guy!". That should make it clear that you don't want to go farther, but still keep the situation in balance. He will probably respond with "Hahaha" and wait for things to develop.

Send him pictures to turn him off, but in a fun way.

Helps if you also say something witty.

Well, personally after that I'd assume he's a guy who's probably only looking to hook up.

That pretty much kills any interest I might have had in him. So I wouldn't bother responding, but that's me.

You could ignore it or try to change the subject. Since you know him and stayed in contact you could probably get away with saying that makes you uncomfortable and he won't run away after that.

Just say so or ok. Or ask why is he telling you this

[JoeCensored]

You basically get to choose between "You realize you just blew it with me?" or "Then invite me over."

He completely misjudged because you guys are not even there yet

Tell him if he wants a pocket pussy for his bday

Text back I am also horny or I'm not horny or I'm horny

[I-Am-Bored]

"Then go fuck yourself"

[Zigzagz]

"Let's fuck"

[Cryostatic]

"I'm not".
