AIBU to get furious with colleague doing stretches on office floor?

[Doingmybestmum]

I am v lucky I work in a job I love with people I like a lot. However I (F) share an office with a man, nice and respectful, who thinks it ok to stretch out on the floor doing yoga type exercises and making loud orgasmy type noises every lunchtime. He is nice and there is no sense in which I feel intimidated but I do think it v inappropriate, particularly as he faces me when he does it. I have suggested that he might be more comfortable doing his exercises elsewhere. He stopped for a bit but has started again. Arggh

I do pressups in the office, but I'm quiet. There's a standing bopper near me too, no problem.
It's live & let live for us. We're mostly weird

Thanks all, agree with juneau that the conference room option is the best. The problem with him facing me is that it is a 2 desk office, and with the door closed and him lying on the floor next to my desk it is very attention seeking. So far so good today but Weallhavewings I will mention it if I have to - hoping he'll stop. If he farts we will have a real problem! I just can't imagine a woman assuming that it would be ok to do this in front of a man, maybe that's why its bothering me so much! thanks all.

You do seem a little unreasonable. Try this though the next time he's stretching

Just say that it is really embarrassing for you. He is rolling on the floor waving about his bits and grunting. If he is as respectful as you say, he will be mortified and never do it again.
