5 days without ejaculating

I (26M) have gone 5 days without ejaculating because I have not had the opportunity to be alone and masturbate as I would like. The thing is that I have had this small exception of escaping at times and being able to see all the stories and comments on reddit, which obviously piss me off and I end up stroking my penis. The thing is that every time I caress myself, I get this incredible desire to ejaculate, but I can't, I'm quite horny, with my cock really hard and standing still, throbbing and preventing myself from cumming. I'm going completely crazy, but when I do manage to ejaculate, I will most likely get a lot of milk and it will be a glorious orgasm.
