Last week, I discussed the need for further education about effective birth control options. So, in what seems an appropriate follow-up, it's time for a crash course in contraceptive methods and issues. They come in a rather dizzying array of options, ranging from foams and jellies to gels and suppositories. They are inserted into the vagina before each act of intercourse and are best used in combination with other forms of birth control.
Spermicides also have the bonus of providing extra lubrication, which can be helpful.
This is one of the only birth control options besides condoms that actually prevents certain STIs. Messy, especially if you're not used to applying them. Also, as stated above, spermicides aren't terribly effective when used alone, instead serving as an effective supplement to other methods. The Pill can cause some side effects, the severity of which depends a lot on the woman. Most are used in combination with a spermicide of some kind.
