is it ok to go outside at 1:30 am when no one is up wearing just as tshirt and briefs underwear

I don't know if it's ok but it sounds very tempting. I'd probably do that if I wasn't afraid of being arrested lol

I sit on my porch in my briefs all the timr

Yes! It's LOVELY!!

depending on your situation you could have gone out butt naked i bet...
