Premature Pregnancy Love Making Threat

It's actually safe to have sex during pregnancy. Your man’s penis can't penetrate beyond your vagina, and the baby cannot tell what's going on. It is normal for your sex drive to change during pregnancy, though. Don't worry about this, but do talk about it with your partner

Sexual closeness and sex are safe during pregnancy, all the way to end. It cannot hurt the baby, who is not aware of what you are doing. Having orgasms does not cause you to go into labor or have a miscarriage. Orgasms can sometimes cause uterine contractions, though. In an otherwise-normal pregnancy, this poses no risk. However, if your pregnancy is at high risk for premature labor or delivery, it is not clear if orgasms that cause contractions may pose a risk; you should speak with your health-care provider.

One worry couples might have is that oral sex might bring up bacteria into the vagina.  This is really only a concern if your partner could have an STD.  If you are in a monogamous relationship and there are no risks of getting an STD from your partner, oral sex is really not much different than the exchange of fluids that happen during kissing.

As you move into the third trimester, however, you may find even simple movements—such as getting in and out of bed, bending forward, and even standing, walking, or sitting—to be very awkward and difficult. This physical clumsiness may keep you from enjoying sexual intercourse. On the other hand, increased pelvic congestion may arouse sexual desires, which are limned by orgasm. Your partner may also feel some restraints in enjoyment. He may be uncomfortable feeling the baby moving while he is making love to you. He may also initiate sex less frequently as he assumes a more protective role. Do not misinterpret this as rejection.
