My boyfriend sucked my toes! Ew

So the other day was my boyfriends birthday and I got some friends together and we had a couple drinks, we weren't too drunk but we were kind of tipsy. After everyone left we had sex, it was literally the best sex ever! But I thought something he did was weird...i looked up for a second and he put my toe in his mouth, then grabbed my other foot and did the same thing. Wtf? Am I the only one who thinks it's nasty? 😩😷
