He's not forcing anyone to share their experiences. Theres no need to overreact. People that dont mind sharing because they can look back and smile at their experiences will be the ones that share. 

By the way you mispelled "embarass" in several places.

I have plenty of such moments, but some of them is impossible to make-public-know hahah. However this one is quite in norm. Once upon of time I have dressed a loose skirt. I went on the loo and after depart of the loo a back ham of skirt stayed cought in my knickers hahhah.. oh

I have embarrassing moments everyday because this is the way of my living. I was absent form classes and I wanted to find out about homewoerk so i go and ask the teacher, he explained it to me, but after 2 min converstation I fond out that he is not my teacher:D

Well about sharing my embarrassing moments I don't mind it at all, actually I have shared a couple of them on italky community and I’d be really happy if you check them out.
There is no one like to embarrass him/her self the way you present it.
I think anyone has moments that love to share with friends or even remember it and smile.
If I force anyone I apologize to all of them.

i signed up to take part in a speech competition. Wenn i was on the stage, i got a stage fright and could not say even a complete sentence. i finished it with a word "sorry", then run away from the stage.
