I always get so horny when I smoke meth. I know why they call it 'gak'. When I'm high on it, pretty soon im pushing my throat onto someone's cock going "gak gak gak"

That's so cool.

One night, a long time ago, a date took me to her place and I was so fuckin horny that when I was lickin and suckin on her clit I suddenly came. I didn't want to tell her that I was done so I just kept munchin and my cock soon got hard again. When we fucked, because I had just cum already, I was able to last longer than the usual 2 or 3 minutes. I think it was about 10 or 15 minutes and I shot another load.

I think what @Thicky means is have you ever had a time when you were going to have a sexual engagement but ended up ejaculating way before the time and/or the wrong place instead of when and where you had intended.
