Is it normal to do things girls do?

Since i was 13-14 years old, I've always wondered what my life would be like if i was a girl. I used to try on my mums underwear and bras and I once shaved my legs and underarms as well. I'm now 37 and married. I recently tried on my wife's underwear and her swimming costume which felt really nice on my skin.
Is this a weird thing to do? Has anyone else done this? Thanks.
