It can. The hormone prolactin, which is boosted by nursing, stimulates milk production, but it may also dampen your libido. You’ll probably also find that you have less vaginal lubrication than you did when you were pregnant, due to lower levels of estrogen while you’re nursing. Using a lubricant will help reduce discomfort you might feel from vaginal dryness. Lubricants are usually found near the condoms or the tampons and sanitary pads in the drugstore. Be sure to get a water-based lubricant, especially if you’re using a barrier method for birth control, since oil-based lubricants can weaken latex and cause a condom to break. Your breasts may not feel like an erogenous zone the way they did before. You may also find that at times they’re too tender for touching or sexual stimulation. Let your partner know how much touching or sucking you’d like. You may worry that your breasts will leak at an inconvenient time – and they might. During climax, some women discover that they experience letdown (their breasts leak or spray milk). That’s because the hormones that are present during orgasm are also present during letdown. If it bothers you, nurse your baby or empty your breasts by pumping before having sex. As time goes on and breastfeeding becomes more established, leaking during sex may not happen as frequently.
