Can your partner feel your IUD?

Has anyone's  partner mentioned feeing a sharp point at the "end" of your vagina? The way he describes it makes me think it's not just the strings and it's the end of my mirena. Anyway, he doesn't really complain or mind too much because it's only every once in a while and we can just switch positions to avoid it but it has been painful for him in the past. I mostly concerned with him moving it from where it's supposed to be!
