I wear DH's underwear. I love them. Boxer briefs. No underwear lines. They are awesome. I have tried the female versions and they arent the same. (No I am not fat, I am a size 12)
I also use mans deodorant. Old Spice, it works amazingly!
And....lastly, I use old spice body wash. The scent I use smells like skittles...I get compliments all the time.
