Which condoms cannot be used?

　　First, let’s look at the pattern style. Condoms with particles or raised threads on the outside can increase the friction and stimulation of the vaginal wall and can better please the woman. In comparison, because latex particles that are too thick can easily cause cracks in condoms, the particle size in qualified products will be limited, which makes the pleasure of threaded condoms more intense than that of granular condoms.

　　Secondly, look at the color and fragrance. Condoms on the market come in various colors, including more than 20 kinds such as red, white, pink, purple, and blue. Since the early 1990s, manufacturers have also introduced condoms with various fragrances, including rose-flavored condoms and osmanthus-flavored condoms. It should be said that the colors and scents are mainly to improve some people's aversion to condoms, and also to increase their appeal. Because people can choose to use different condoms based on their color preference or their mood at the time.

　　We need to remind everyone that the popular strawberry, chocolate and other flavored condoms can easily cause vaginal inflammation in women. If you want to choose this type of product, be sure to pay close attention female If you have abnormal vaginal discharge, use it as little as possible.

　　There is also a "glow-in-the-dark" condom, which uses phosphorus-containing paint to produce light to increase sexual interest. Phosphorus is more allergenic. You must choose carefully according to your own situation and do not blindly seek novelty and difference. 》》》Which sex positions are most likely to lead to pregnancy
