Ribbed condoms have little raised ridges running around them that have been strategically placed to increase sensation during penetrative sex. Although rib-only condoms are available, dotted condoms or condoms with both ribs and dots are also available.
Dotted condoms have dots running the length of the condom to add extra dimensions of stimulation, whereas ribbed and dotted condoms have both ribs and dots.
Ribbed and dotted condoms are not only intended to provide the same level of protection as regular condoms, but they are also intended to increase the sensation when used.
The ribs and dots along the shaft of the condom contrast with the typically smooth surface of regular condoms, allowing you to get more out of sex.
