I think it depends upon what sort of relationship you have, if I were preening in front of the mirror I think my husband would tease me in a jokey way but we have a well established secure relationship and joking and teasing is part of that (we laugh at ourselves rather than at each other if that makes sense).

As you have only been seeing this guy a short time Eve and not too serious yet it's your judgement call on how he will take gentle teasing like Seesaw describes.
