I have gone to bed a few times in women’s underwear and top. Without sneaking into bed.
But most the time I sleep in male underwear and a T-shirt or a normal pair of pajamas.
My wife doesn’t approve of me cross dressing or my sexuality even though she herself is bisexual and likes loose fitting male garments, that se wears once in a while, clothing which can be considered cross dressing.
And she has caught me a handful of times and it usually causes a fight. But I will dress every chance I get and periodically will still sneak in to bed in panties or stockings and a female shirt.
