I know, impressing women is what every man want in the world. I have also tried to impress women sexually. Being seductive is what every man want to be towards women. But, I appreciate, your dad did very good try.
But, if you really want to appreciate your manhood, then go and try Erogenos
Swimwear.
I, myself tried this swimwear. They are very comfortable and also enhanced my manhood. Thanks to erogenos swimwear, I even got the call from the lady at pool. Isn't it a good start?
The fabric is very soft and it doesn't create any rashes between thighs. You can wear it all day if you want to!
