Condoms are designed and tested -- each and every one of them, by every manufacturer -- to be able to withstand ejaculation what you're calling "erupting" as well as to contain a single ejaculation: the amount of semen a person with a penis emits when they ejaculate. They test them by blowing amounts of air into each condom with a level of force called "airburst tests" far greater than the kind of force which occurs when a man ejaculates. If you look at a condom, you'll see that at the end of it, it's shaped a little bit differently than the rest, with a tip that kind of looks like a long nipple. That "reservoir tip" you'll often see mentioned on condom boxes and in their instructions is the part of the condom built specifically to hold ejaculate or "cum". When you put a condom on, so long as you do so properly, leaving that tip hanging off the end of your penis, and pinching it to remove any air bubbles, it's totally fine to ejaculate while you are inside a partner 's vagina , anus or mouth. Just be sure you're also doing other things that help condoms stay intact, like using extra lubricant with your condom, using good quality condoms that aren't past their expiration date and storing your condoms in a place where they'll not get overheated, frozen, or beat up by being carried around too much. That isn't to say that a person can't withdraw with condom use if they are more comfortable with that. Just know that it can actually make your condoms LESS effective to do so if you do not remember to hold the base of the condom when you withdraw. Holding the base of the condom as you pull your penis out of any orifice is important when using condoms whether you withdraw in advance of ejaculating or not, but it can sometimes be easier to space out holding the base when you're in the middle of orgasm or about to orgasm, since at that point in time, most of us have an understandably tough time thinking clearly.
2. Mistake: You skip out on STI tests because you've been using condoms regularly.
When it comes to using condoms, you probably have questions. And: Can sperm leak out the base of a condom? Yep, pretty sexy stuff. But it's OK to have those questions, because the more you know about how to use condoms, the more likely you are to use them correctly. While condoms can play a key role in protecting you, they're not the be-all and end-all of safe sex. Levine, M.
The rest of them put it on after some genital contact or took it off before they finished. This is a big problem, because any skin-to-skin genital contact can lead to STIs. So put it on right at the beginning, and keep it on until you're finished.
Yes, that is the basic purpose of a condom. To allow the man to ejaculate inside a woman while removing most of the risk of pregnancy. About 15 out of every couples who have regular sex for a year while using condoms get pregnant. If you want more certainty, you may want to use another method of birth control in addition, or instead of, condoms.
