Once my sister walked in on me (I was in my early teens). I walked in on her once, about 6 months later. Both times were under covers, but it was still fairly obvious. So we’re square. Other than that, no.
All accidental, if that wasn’t clear. After these incidents, we **always **knocked first.
No, but I walked in on my ex once. I got off work early, and walked in on him having phone sex with someone. Very awkward moment. Funny in retrospect.
Uhhh… Not quite yet… Gimme a couple more minutes…
“Who can come first” competitions among teenage boys are described in Everything You Always Wanted to Know about Sex* as “ironic,” considering that as adults, most men would prefer greater endurance.
Does it count as “caught” if you’re running up to people while doing it?
My wife is a member of a bulletin board on which was a thread “what would you do if you caught your husband masturbating?” She told me that many of the women would take immediate offense and seemed to jump to the conclusion that there was something wrong with the marriage and counseling must be sought immediately.
Further she volunteered that if she caught me masturbating, she’d join me saying something like “need some help with that, big boy?”
She’s “caught” me more than a few times since that revelation!
Not yet. 
Seriously, I don’t understand why some people seem offended at the idea that their partner might “catch” them… it’s hot!
They’re not offended at the idea of being caught, they’re offended at the idea of catching their marriage partner at it.
You did it a lot to your neurologist? 
No, but once my mom raided my room, when she came to visit. I was in the shower and she started searching my room, after she heard rumors about my sex life.
She found my vibrator and confronted me about it. She asked my why a woman in a relationship would have a “self stimulator”. I died of embarrassment. 
Your mom should be friends with my mom, she went through my stuff constantly. That’s why when I was staying at her house for a few terrible months in my 20s, I put my stuff in my storage unit.
Another time when I was in my 20s she was helping me move and found a condom and “confronted” me about it. I tried to get all my personal stuff and put it in my car before the people came to help me move but it’s easy to miss a couple things. One more reason I despise moving!
Going at it in my college dorm room, late one Friday night when my roommate was away, when I noticed a buzzing sound. I pulled up my clothes just as the RA (dorm supervisor) walked in. It was the building’s fire alarm, and he had to check all the rooms. That was the last time I did that while wearing headphones!
You should look into a better lubricant if your setting off fire alarms “going at it”…
Yes I have , and Woolworths banned me from all of their stores after that .
In other words, you almost got caught. Or did he realize what you had been up to just before he barged in?
