How often do you masturbate?
A lot less since you control my orgasms

Used to be almost every day, a lot less now, maybe once a week.
It varies, but often I don't use any toys. If I do it's generally the anal toys, plugs, vibro balls, or now my new prostate vibrator.
Nope
Do you watch porn or read erotica while masturbating?
Generally watch porn. Sometimes reading a bit of erotica to get me started, but as I get excited I lose the ability to read, and sometimes it's just not enough to get me over the edge. It's more efficient to have something that keeps going on it's own with very little cognitive effort from me.
How long do you usually take to masturbate?
10-15 minutes... although lately, when i finally get my orgasm, it's closer to 2-3 minutes.
Where is your favorite place to masturbate?
At my desk, comfy.
What is the weirdest place you have ever masturbated?
At a friend's house, when they're asleep I'd sometimes nip to the bathroom and rub one out.
Have you ever been caught masturbating?
Nope.
Do you always orgasm when you masturbate?
Generally yes. There was one little period when i had a different brand of antidepressants with a different side effect. My usual ones make me sleepy, but those caused delayed orgasms. I could get started, but i couldn't finish. I tried until both my arms were sore but I just couldn't get there. Took days of trying before i finally came. Teased and denied by own happy pills, what a betrayal.
