For my wife it would be 1. My wife has no uterus, so she never has used birth control and never has been fucked with a condom 2. She has only ever had 2 sexual partners (only three of us know that info) 3. For close to a year the only penitrative sex we had was anal 4. She really didn't like giving oral, but after time she figured out that there is only a couple of positions she likes since my cock is above average and it hurts 5. Since she doesn't have a uterus, the only difference really is that she is so tight when I first penitrate her it hurts, if you go slow and feel the spot, you push the cock against it then it opens up and let's say the flood gates open and you can fuck her like crazy
