Mine was loyal to.my
father because he was dead serious about fidelity. I will never know if he cheated on her at least once, or she on him (the latter I doubt)
However, my mom is 70 years old and talking with a 40years old cousin of mine, they were watching a video about a very big snake and my mom made a joke about it being a giant penis and my cousin giggled shyly. And I was right next to them.
Also when showering my brother's male pitbull, my mom touched the dog's penis with her hand occasionally while cleaning with soap and water. I doubt she acknowledged it as something sexual but I still think it's a pretty weird thing to do
