You can do whatever the hell "feels good" to you, but I maintain my right to state it's unnatural and, tbh, a bit revolting.
I also hate how men manipulate women, having women perform unnatural acts for the twisted gratification of men. I hate it. Women ought to be honored and respected. Moms ought to teach their sons to honor and respect women, and for their daughter's to not be disrespected, or treated like pieces of meat.
