Some men can't maintain an erection
I am 59 years old. The reason why some of us women engage in self-pleasure is because the men can't maintain a good erection. Their erection is weak and it is very soft. So we, the ladies, have to help ourselves by using the dildo.
Any woman who has a man who cannot function well should be encouraged to go and see an urologist. So if your man is suffering from erectile dysfunction, please encourage him to go to see the specialist. I need not comment on your dildo.
