As one of the other posters noted I don't carry a tape measure so I'm taking a best guess at size. I really should carry measuring tape based on the questions about cock size ..
When I was in college and high school, there are a few guys that I would not let go deep. You can probably imagine how thrilled they were with that. Now that I'm older and am a mom, I think my vagina is larger and more accommodating. I welcome the challenge of really big ones. I find that big ones tend to work better in some positions better than others. The big dick guys tend to do a better job fucking my pussy from behind as they have to deal with my big butt that may get in the way.
Most guys are too large to comfortably fuck my ass. However, if the guy has a short slender cock, it feels great! Seriously, I'm talking about skinny cocks that are 5 inches or less have felt great in my butt. I'm finding myself getting wet thinking about it ..
