Assuming you have no restrictions during your pregnancy, sex will not hurt the baby. It is important for you and your partner to remain intimate throughout your pregnancy, however sexual intercourse is not the only way to express your love for each other. Hugging, kissing and just cuddling can be very satisfying.
Mutual masturbation is also an option.
Communication is the key for maintaining a positive relationship with your partner during pregnancy and after childbirth. Having a baby can be a very exciting time in both of your lives but can also put a strain on your relationship. Tell your partner what your wants, needs and desires are and encourage him to do the same. Concern for each other s welfare goes a long way during times of stress. If you can arrange it, make a date on a regular basis to spend time together even if it means taking a walk together or going food shopping.
