For straight guys:

I'm straight, but sometimes watching girl solo porn doesn't turn me on. Also, if I see a boobies picture or something I probably won't get turned on. Yet, in a real situation I get turned on. Has this happened to anyone else?

yea it happens to me but i don't really watch porn any more

It doesn't mean you're not straight, it just means that you aren't turned on by a bunch of pixels on a screen.

[Kobra]

Happens to me too

[SwimRunSleep]

Same here.

It's happened to me from time to time. It's normal.

It's the opposite of video games. So many people play Call of Duty and have fun with that but if they were caught in a real situation with a bunch of guns going off, I am pretty sure they would be bawling their eyes out. Things are so much different on a computer screen.

It happens to me. Its totally normal. Don't worry about it.

omg I am the exact same way lol. If i watch a girl masturbating on a porno, it doesnt do too much for me (sometimes), or a naked picture of a real hot girl, is eh. it's all about context is seems.

If I see the naked picture in the presence of a friend, or my gf or something, it will probably turn me on. Or if a guy is in the porno, watching the girl, I'll probably get turned on. I think it has to do with us rationalizing the picture, and essentially desexualizing it, similarly to how "art" is often times nude depictions of people: that's not sexual or rather not made to arouse.

By looking at a naked picture, or solo porn, by yourself, your brain doesn't equate the image with a sexual response. No sex is about to happen, so why become aroused. Does that make sense? Where as with another girl (in real life) or with a guy (in the video) a sexually suggestive image is created; the possibility for reproduction becomes more realistic. Does that seem reasonable?

Kind of just thought of that as I went..
