Some people are natural-born parents. They could nurture rocks into boulders; they are just that good at it. Other people struggle a little, but they still make good parents because they love children and love their own children very much. Then there is the group that absolutely does not want children and would not make good parents because they do not want children. If you fall into this last group, here are some permanent forms of birth control for you.
Two months after a vasectomy there are no sperm in a man's ejaculate. While the effects are not immediate, they are permanent once they have set in. For the first two months your partner will have to wear a condom, but chances are, he will not be interested in sex for the first two to three weeks while he heals from the surgery that cuts the cords between his testicles and his prostate.
Most OBGYNs are apprehensive about tying a woman's tubes when she is in her 20's. However, if you are quite adamant that you do not want children, your OBGYN can perform the surgery. It is much more invasive than a vasectomy, takes longer to heal, and (unlike a vasectomy) is completely irreversible. If you time it just right, then you will prevent any eggs from traveling into your Fallopian tubes and uterus, thus making you ready for sex without risk of a baby almost immediately.
There are small metal devices that your OBGYN can implant in a female's Fallopian tubes to permanently prevent pregnancy. These implants cause your body to create extra tissue, which grows up, in, and around the implanted devices, thereby cutting off the paths from the ovaries to the uterus. Like a vasectomy, you will need to use a backup method to prevent pregnancy until the devices are fully engulfed in tissue.
This is definitely not everyone's favorite form of permanent birth control, but it is the most effective. You cannot get pregnant if you abstain from having sexual intercourse completely. If you are not a "one-night-stand" type of person, and you currently have no special person in your life, then this is actually quite easy to do.
This is definitely not for everyone, but it works just as well for preventing pregnancy as abstinence. Same-sex male partners cannot impregnate each other, nor can same-sex female partners. Just make sure your same-sex partner is on the same page as you with regards to not having children, or not remaining in this relationship for very long.
