Things a Guy Can Do to Prevent PregnancyJust because men can't actually use most forms of birth control doesn't mean they're entirely off the hook - at least not if they want to avoid an unwanted pregnancy and the risk of exposure to sexually transmitted infections. Safe sex involves two responsible partners. So what can men do to make their sex lives safer? Here are a few tips.
Wear a rubber - every time - unless you’re confident your partner is using a reliable form of birth control. With new partners, casual partners, or non-monogamous relationships, it's best to always use a condom, regardless of her birth control. (A condom works best when you put it on right.

Offer to Pay
Your lady may have to take the pill, but you can always offer to pick up refills for her. Birth control can be expensive. You’re both benefiting from it, so offer to split the cost!
Learn about contraception, research the different types of birth control and understand how they work. That way you'll be able to have an educated discussion about it with your partners. (Get started on research by reading We Asked An Expert: Which Birth Control Is Best?)
Offer to Help
Ask your partner what you can do to help make it easier for her to use her birth control. Does she need a ride to the doctor’s office or the pharmacy? Does she need help remembering to take her pill? Again, birth control benefits both of you, so offer to give your partner any help she requests.
Don’t Have Sex Without It
If you don’t have a condom and she isn’t on birth control, wait until you do. Don’t ever pressure your partner to have unsafe sex (or any kind of sex for that matter), and refuse to put out if she pressures you.
Make the Cut
If you're absolutely certain you don’t want to have children, or you have as many as you want to have, then a short procedure with a physician can prevent you from getting your partner pregnant permanently. A vasectomy isn't 100 percent effective, but it’s pretty close. Make sure to do the follow-up test a few months after the procedure to ensure it worked, and use a backup method until you have that confirmation. Also keep in mind that this will not protect you against sexually transmitted infections. (Sometimes, vasectomies reverse themselves.
