Sex during pregnancy: An unnecessary taboo?

If you want to get pregnant, you have sex. No surprises there. But what about sex while you're pregnant? The answers aren't always as clear. Here's what you need to know about sex during pregnancy.

Is it OK to have sex during pregnancy?

As long as your pregnancy is proceeding normally, you can have sex as often as you like. But you may not always want to. At first, hormonal fluctuations, fatigue and nausea may sap your sexual desire. During the second trimester, increased blood flow to your sexual organs and breasts may rekindle your desire for sex. But by the third trimester, weight gain, back pain and other symptoms may once again dampen your enthusiasm for sex.
