Maybe not so much a gay/str8 thing but a generational thing? Mom had a ton of pictures but limited hanging stuff to the walls of her home office and a few framed standing pictures here and there, not overdone at all, though in the office were collages including most all of her 60plus relatives.
I have mostly just my immediate family plus grandparents as does my brother and his wife. The rest is on the computer or in photo albums I've yet to scan.
My dad's place is ton of framed pictures on the walls of most rooms (I'm pretty sure that's his 3rd wife's doing) plus a digital frame plus what's on his puter.
An older neighbor came by recently, saw the pic of my mom and wanted to see more so I got out an album. Flipping through the pages, turned the wrong one, ooops, my 1st partner mooning the camera, maybe that should go on the wall?
Then she took me to her place--I was planting a tree for her--and inside her home the walls and piano were covered in pictures. A very goodlooking family. One of her son was stunning and I couldn't take my eyes off it. Sadly he committed suicide. Her husband looks at his photos all day long wondering how it is that he's living this nightmare.
I think that's partly why I don't have a lot of pictures. I can't be reminded at every turn of so many who I've loved and lost.
Here's the table at my front door, these are the only photos in the living room, my mother to the left and my grandmother to the right....
I've got others in the breakfast nook and in the hallway to the bedrooms. No more than that.
