I had sex for the first time a few months ago, and then with a second person last week. Both times the condom broke and I'm not sure why. The school I go to doesn't have a sex ed program, so I'm sort of just guessing at how to use one the right way. Neither of the people I've been with really knew the right way either. I watched a video on youtube, but it wasn't super helpful. I understand how to put one on, I think, but they still break. Any ideas?
1. It's great that you're really focused on using condoms. 2. Condoms can be tricky! Penises come in different size, so do condoms. You may have to try a few different brands and sizes to find the one that fits you best. In terms of breakage, condom size can actually make a huge difference, mostly if it's too tight. It's also possible for the condom to be too large and the latex rubbing on the latex can also cause the condom to break. Are you making sure to squeeze the tip of the condom while putting it on? It's important that the tip be there not only for ejaculate and pre-ejaculate, but also for space inside the condom to allow for movement.
What about lube? Lube is extremely important. When using a condom, either latex or polyurethane, ALWAYS use a water based lubricant. Oil based lubricants can cause a condom to break. The vast majority of lubricants will make it extremely clear what kind it is, usually it says so right on the front of the label. Make sure to use plenty of lubricant as the condom getting too dry can also make it break.
How are you opening the condom? This seems like a silly question, but it's possible to tear the condom when attempting to open the package. One way to ensure you're not tearing the condom when opening is to push the condom all the way down to one end of the package, then tear open the top, where the condom isn't. Do not open the package with your teeth. I know it looks super sexy in porn and in movies when someone casually opens a condom with their teeth, but you're also risking tearing it with your teeth.
Do you check the expiration date? Condoms have expiration dates in tiny print on each pouch. Make sure and check the date as older condoms are more likely to break.
If none of these things seem to help, then I suggest trying an experiment. Wear different condoms when you masturbate and see if any of them break that way. If some do and some don't, investigate why. Is it the type? Size? Lube? A little bit of trial and error on your own won't put you or your partners at risk.
