Wearing condoms can play a role in protecting against warts, but it is not 100 percent effective in stopping the spread of warts. Warts are a sexually transmitted disease caused by human papillomavirus infection, and contact with other parts of the body, contact before a condom, and contact with the clothing and utensils of a person with warts can increase the risk of infection. Therefore, if you have warts, you should give them prompt treatment so that they do not increase in number and size, and also try to avoid sexual contact, and only consider having sex again after they have been cured. The same syphilis, AIDS, gonorrhea and other sexually transmitted diseases wearing a condom is not able to do a hundred percent blocking, so the best way to block sexually transmitted diseases is still clean, avoid unclean sex. If you have high-risk sex, you should go to the hospital for regular checkups to avoid contracting the above mentioned STDs, or to get timely treatment.
