There are thousands of toys that can maximize sexual pleasure with yourself or a partner. For a VERY GENERAL overview,
Vibrator: Used for external stimulation, usually of the clitoris, tip of penis, or other parts of the body.
Dildo: Used for internal stimulation and come in many sizes. Usually used for vaginal penetration, anal penetration, and strap on play.
Dual Toy: Penetration and external vibration combined, usually referred to as "rabbit". Great for ultimate stimulation of clitoris inside and out.
Butt Plug: Toy used to stimulate anally
Prostate Massager: Used to stimulate the prostate through an insertable toy.
Lubricant should be used during sex or self pleasure for added comfortability, enjoyment, and durability.
Water Based: Safe to use on silicone toys, absorbable, will need to reapply during experience. Recommended for vaginal penetration and play. Condom compatible.
Silicone Based: Great for long lasting play and most ideal for anal play. Not safe to use with silicone products, condom compatible.
Hybrid: Silicone/Water based lube mix, great for non silicone toys and more absorbable. Condom compatible.
Oil based: Long lasting and natural, but not condom compatible.
Avoid: Non-organic Lubes with ingredients like alcohol, glycerin, or preservatives.
Latex: Non-Permeable, protects against STI's and pregnancy. Some have allergies to latex.
Non Latex: Protects against pregnancy but is permeable, not full protection against STI's, better for allergies.
Polyisoprene: Substitute for latex condoms, prevent pregnancy and STI's
All condoms can be put over sex toys to be used on different partners to prevent spread of STI's.
Dental Dams: Used to place over vulva or anus during oral sex to prevent STI's
Latex Gloves: Can be used to protect hand during fingered penetration.
Regular STI Testing: Should be done every 3 months, and in between new partners.
Boiling: Great for non battery toys like glass or silicone toys, full sterilization.
Sanitation Products: Sprays, liquids, and foams used to clean your toys. Apply then rinse with water.
I recommend only using organic toy cleaners.
UV Sterilization: As pictured, a 99.9% way of killing all bacteria, viruses, and yeast. UV light bulbs provide secure sterilization in 10 mins.
Storage: Recommended to store in silk bags to keep off dust. Better to not let silicone toys touch each other, as touching silicone can break each other down.
