A condom can protect against STI while having
sex and can help you last longer. It also serves as a birth control but it is recommended to use another birth control in addition in
case a condom breaks. Additional lubricant may be necessary to avoid breaking a condom. Some condoms are a bit thicker, which can improve security and stamina. If you have a
casual partner, condoms can also be used for a blowjob to prevent STI. Usually condoms are already lubricated but there are condoms without lubricant in
case the girl does not like lubricant for a blowjob. If you want to have a threesome but don't have
female condoms, it is recommended to use one condom for each girl, to avoid sharing an STI between the 2 girls.
