On facial expressions...

My girlfriend pointed out to me how odd it is that I don't have a facial expression when I... errr... finish... I've seen faisal expressions in hentai and porn, I've seen women make them (hers is... interesting... kind she just are something sour), in media form I've seen men make them, but I don't have an expression, it's just a typical poker face. In ordinary situations do guys have a particular face for it and I'm just weird or what?

Wow Really? o.o
That takes talent!
I know i couldnt hold a straight face cause everytime i get it off its like this.

Ahegao or generic open-mouthed, eyes closed.

I don't think i do either.

If your face isn't neutral in every single situation you come across, you aren't living life correctly. Just saw the most disturbing thing in your life? Neutral. Best thing ever just happened? Neutral. Planet you're on blowing up? Tell the nearest person to tell your wife "hello" if you die. No other way to do it.

Had to ask...

For some odd reason it reminded me of this video.
I blame you.
._.

poker face. maybe eyes closed, but nothing much :\

I can make funny; derpy faces, But for emotions, My expressions are so weak and loose that I have as well call it a poker face.

Honestly, I never have a change of expression when I masturbate, Only poker face from the the beginning till the end.

Maybe you're simply unable to show emotion in your face?

In every other situation I'm very expressive, it's not quite like that.

I don't think that you are weird. Some men just don't.

It's natural to want your partner to have a good time too, and a way to know that it's through the expressions and sounds. So maybe your girlfriend is a little worried. You should tell her that's your normal reaction and that you're really feeling good when you're at it.

The sex is kinda meh... I've had better...

Ouch. Why? You should communicate with her - don't tell her she is bad(!), but simply tell her things you'd like to try, or perhaps initiate a conversation after your sex sessions. Go over things you liked or didn't like so much, so that she knows what to focus more on in the future or discard what you'd rather not experience again. If she doesn't know how to make you happy or she believes that you're already satisfied, then it won't improve much. It is good to do this regularly, so that you begin to know those things that really send your partner over the edge. I'm sure this conversation will teach you a lot about your girlfriend's preferences as well.

"move more damn you!!!!!"

I think that ought to cover it...

Where would he show emotion then, if not in his face o.0

Maybe through his voice?

Mostly silent, years of sneaking in rooms next to parents, barracks latrines (shower, yes with a female), church parking lots, etc have gotten me to be silent by habit, then again I was never known to be noisy...

So basically you a stone-cold killah man?

Or someone like Agent 47?
