Ribbed and dotted condoms don’t come with any particular risks, except a higher risk of irritation if your partner has sensitive skin or if you don’t use sufficient intimate lubricant.
Textured condoms made of latex can also cause allergies. If you or your partner are allergic to latex, simply use a non-latex condom. Whilst options are limited, SKYN, the most popular brand of non-latex condoms, manufactures a type of textured condom suitable for people with allergies or those who can’t stand the odour of latex.
