Better erection from oral sex due to nitric oxide in saliva ?

Interesting theory guys, might this be the reason why we get insta boners when a girl sucks us or is all in mind ?

Nice thought. However, you need to have the nitric oxide in your blood to experience the benefits. Perhaps you can arrange for a vampire to suck your dick.

It might be they have nitric oxide in their eyes as well because when they look up at me down there I get a little harder as well. Not sure why.

Hot girl with my member in her mouth going to town V's ......... my hand.

Yeah I know which one gets me harder and it has nothing to do with Nitric oxide in her saliva!

Hmmm. Next time I nick my shaft or balls shaving I’ll have her lick them. For medical purposes only.

Nah, it's because saliva contains growth factors, like VEGF, that make the penis grow. Just kidding, it doesn't work that way. I think I get a great boner when she goes down on me because I love blowjobs.
