If women put out and where not looking for the charming prince and men were not looking for the hot supermodel then masturbation would be an activity no longer performed alone, maybe its not the act that is making us blind but the way the act is done "alone"
Self love is free, it doesn't involve organization, it doesn't need to be booked, or is booked out when you require it, or closed which is awful and worse than previous statement, it doesn't get jealous or annoyed if you go a few days without self love, if you leave the toilet seat up, don't do the dishes , miss bin day or even a birthday self love can still occur, self love means never listening to a mother in law, or putting up with uncle bobs queer looks at you, self love doesn't care if you come home with a brand new sports car, or a new pair of heels, self love is open 24/7 even with a few drinks a 3 day growth self love can be just as great as sober and smooth, so you may end up blind there are always pluses and minuses about activities if you end up blind self love would take on whole new meaning and you could self love anywhere without guilt as the you could claim a disability and say I thought I was stroking my blind aid stick or rubbing the stop button on the bus, and without embarrassment either, the then bonus is if you get arrested for a public display of self love you can still continue or finish this off back at the lockup as the equipment is always easily accessible.....
So self love versus a partner does have its bonuses...
