Is it normal to not like sex with more than one person at a time

ive been starting to feel more and more like a total weirdo lately because I feel im the only one on this planet that doesn't ever want to have group sex.
never had any desire for it, I don't think I ever will.
I am into thinking about reverse cuckold with my dude so no its not a jealousy thing.
it just seems retarded, unless its choreographed and rehearsed ahead of time like porn is.
maybe im not good enough in bed because if I spread my sexuality around too many people the pieces all those people get aren't shit compared to when im with one other person without interruption of someone taking the pleasure away from me because they want their turn?
