The guy I (29F) am dating (29M) told me he likes to crossdress

So, im mostly okay with it. Like 99% its just leggings and he likes smocked tops. He has a nice dress and a few other things. To be honest, he looks really good in legging and i have told him that (i always liked men in tights when I was younger). I shouldnt really be surprised since I noticed he doesnt have much body hair, but still.

Im mostly just worried if it means something more? Im just worried that he might end up holding back that he is gay or trans? I dont want to end up marrying someone and 10 years down the line he reveals some bombshell like that.
