One of the great things about strap-ons is that anyone can use them. If you have a penis, you can use a strap-on. If you don't have a penis, you can use a strap-on. You can use a strap-on to penetrate a partner of any gender, to subvert stereotypical gender roles or to play with those roles. You can use one for fun, or you can use one to manage erectile or orgasmic challenges. You can use a strap-on for vaginal sex, anal sex, oral sex, manual sex or masturbation.

Female ejaculation – commonly known as "squirting" – has been a subject of interest right back to ancient times. Back then, however, it wasn’t a puzzle or taboo. The philosopher Aristotle, who was kicking around Ancient Greece more than 300 years BC, matter-of-factly observed that when women ejaculate, they produce far more liquid than men. And the Kama Sutra, the Hindu sexual text written around 200-400 AD, called the product of squirting ‘female semen’. It’s clear that for some of our ancient sisters ejaculation at orgasm was a normal part of sex.

There’s a lot of buzz about strap-on play right now. With the general (and wonderful) climate of increasing openness about all things sexual, both women and men are wanting to explore their play options. Strap-on play is a fun, hands-free way for a person (either male or female) to penetrate a sexual partner (again, either male or female) with a dildo. ‘Pegging’, where a woman penetrates a man, has especially grabbed lots of media attention recently, but strap-on play is great for any combination of partners, and for both vaginal and anal stimulation.
