Wow you are an extraordinary man Tlaloc, you get a full hard-on right off the bat? You know being horny isn't a black and white / on-off affair. I might feel horny, but doesn't mean I have a full erect penis in my pants.
You don't need to 'inspire' yourself a bit? I mean if you don't that's great, all the power to you man!
If I am "horny", the erection comes easily... unless there is some anxiety blocking me.
But if I am by myself, what sort of anxiety might block me? :S
