I think these look great on you but you should try multiple styles and mens underwear comes in so many different materials now. I have modal, polyester, bamboo boxer briefs (my preference). Explore. Post more photos when you have styles that you feel sexy in.
I don't wear white briefs anymore, but Jockey remains one of my favorite brands for quality and love the way they fee. This photo reminds me of my many jerk off sessions into my white Jockey briefs.
Back in high school and college all I wore were Jockey Y front briefs. I remember them as being very comfortable, and that unlike other briefs I had worn Jockey provided more room for the cock to hang more forward. I may have to break down and buy a few pair for old times sake.
Good for you. While I do not really think it is appropriate for an area where there might be young children, I certainly think that adults should be adult - there is nothing wrong with public nudity.
