If you and your partner are pregnant (yes it's a couple thing not just a woman thing) then you'll be pleased to hear how important it is to continue to build intimacy through your sexual relationship during pregnancy.
Of course, not all women get that amazing sexual drive in pregnancy, and for some the thought of sex is a bit ho-hum. But it's worth perseverance ladies, it's a critical time in BOTH your lives.
As your baby will impact on your relationship, filling up the emotional love tank while you're pregnant is a good idea. There'll undoubtedly be a period where that will be difficult in the early stages of a new baby so it's super important to look after the relationship while you have some time.
