If you were at a party with your boyfriend and another male friend offered you their jacket would you take it?

My boyfriend and I were at a BBQ. I was in a spaghetti strap top. Later in evening our friend asked if I was cold and offered his jacket. I said I was fine and no thank you (it seemed wrong to take another man's jacket) out the corner of my eye i saw my boyfriend's irritation of our friends offer and he smiled when I refused. About 20 min later my boyfriend gave me his jacket.
Ladies would you accept a friend's jacket over your mans?
Gentlemen would you be angry if your lady took another's jacket. ?
