Many men have this doubt! Generally, the instructions on the condom will say "Pinch the small bag at the front end and squeeze out the air", and then slowly roll it on the penis. In actual use, experts will recommend that men leave about 1 cm of space at the front of the condom (including the small sac) to "hold" semen. If you leave too little, it may cause the condom to gradually "grab" the penis during sexual intercourse, increasing discomfort; if you leave too much, the condom will slip off.

Some people may say that it is enough to leave the same amount of space for different amounts of male semen. Modern research has proven that the volume of male semen is mostly one tablespoon, which is as much as a mouthful of phlegm, and the difference is basically not much.

I also suggest that men who don’t know how to use condoms may find an opportunity to masturbate with condoms. In this way, you can intuitively feel how much space should be left, which will not make you uncomfortable, but also ensure the effectiveness of contraception. In addition, the design of the small pouch at the front of each brand of condom is different, and some are longer and larger. Although this will not be written in the product manual, men can consult the company or seller.
