Oldest dildo :: The oldest dildos were found in tombs of ancient Egypt. They were made of loam. As Egyptian aristocracy was buried only with the most valuable things (which could be useful in a better world), so it is obvious, that dildo was of a great importance for Egyptian women. For material considerations not so much dildos were made of gold or silver. In the Middle Ages sealing wax was widely spread. It absorbed body warmth and became a little bit soft creating natural sensation. Primitive tribes used loam: unglazed for common people and glazed for leaders wives. During active use loam could break to pieces what led to painful procedure.
Using warming lubricants :: you can apply it on every part of your body. For additional sexual pleasure, you can rub warming lubricant into the breasts or the buttocks. Give the warming lubricant a minute to heat. You can massage it to increase the warmth. Blowing on the genitals after warming lubricant has been applied, intensifies the heat. If you notice any irritation on skin after applying a warming lubricant, stop using it. Maybe it is allergic reaction. Anyway, consult with a doctor. You can also choose a flavored warming lubricant.

Every time :: using strap on don't forger to use lubricants. Dildo and genitals of your partner have to be lubricated. Try different lubes to choose the best for strap on games. At first active partner should refrain from rough pushing hips movements. Position from behind is convenient for this purpose. Some prefer fellatio simulation when passive partner sucks dildo. If it is inserted into anus, don't put it into mouth without cleaning dildo with warm water using special cleaners for sex toys or soap. If active partner is a man, he can penetrate partner in turn with his own penis and strap on. If strap on is used by both man and woman, the variant of double penetration is applied, when man penetrates into vagina and anus with penis and strap on. If strap on is used by woman, its front part is just opposite her clitoris. Dildo shaft, pressing to the body, provides light clitoris stimulation, which gives much pleasure to women.
