We're about the same height. She's plus size, and I'm slim-ish. There are no positions that we straight up can't do, but there are limitations. Our similar height actually makes sex standing up pretty easy.
For PIV sex, I need to be aware of my angle so I don't ding her cervix. She also needs to be very turned on and lubed up before I can go in due to my girth. So no quickies unless she's really horny already (which is rare due to life stress).
We haven't done anal because of a very shit experience with her ex.
Receiving oral is good, but there's always the danger of teeth. There's no issue of my giving her oral.
Nothing sexy this weekend. I cleaned, read a book, and took the family to see Labyrinth at the theater. I think my wife and I were the only ones enjoying ourselves.
