Virtually, a strap-on sex toy can be used in any sex position. Here below are suggested the most popular positions you and your partner can practice during your sexual encounters:
Missionary position allows both lovers to look in their eyes, kiss and do many other intimate things like fondling, whispering tender words, touching, etc.
Doggy style. The very position guarantees deep penetration and is easy to perform. Doggy style is perfect for both anal and vaginal sex.
Bent over. That's a sex position used for pegging and implies penetration from behind. The position is great for prostate stimulation which comes with orgasmic sensations for many men.
