I can acheive a full on erection without the need of my prescribed sildenafil (viagra), although at one time in the recent past I did suffer from ED.
Now, I take one prior to sex, just in case my nerves kick in, and so it alleviates any form of nervous tension.
There have been days when I wake up as horny as hell, I have quite a few hours of being alone so I can wank and edge for hours on end. I take a viagra before breakfast, and the mere thought of sex gives me a solid erection.
Now, you may say, that is exactly what the drug is meant for.
I take it because, I like the feeling of having an erection even after cumming. I sort of want to force my penis into being erect while watching or reading porn. I get addicted to masturbating. Along with the viagra, I often use estim on my cock. My cock may feel exhausted, it wants to go to sleep after orgasm, but no, I use the estim to force it to erect, again and again. I like to bring myself to orgasm over and over. The orgasms are of course dry and painful. My empty prostate thudding away as I orgasm again and again.
It is the feeling of the external control of my cock which I love. As if the viagra and estim are dominating me. I want to say no, stop, my cock does not want to erect any more, it is worn out, but I FORCE it to erect, repeatedly to dry orgasms.
How I would like to have a session with a Mistress or Master, whereby I am restrained, and given this treatment for hours on end. They will be controlling my erection, forcing me to orgasm against the natural will of my cock, and of course, verbally humiliate me as they watch my forcibly erected, exhausted penis being brought to a dry orgasm.
