When I was baby I didn't get breast feeding, will this affect my sex life?

No. Breastfeeding or lack of it will not affect your ultimate sexuality. The major benefits of breastfeeding are supplemental immunity and digestive aid along with closeness between the mom and baby.
NO. No. But when you have your own children, please try to make sure that they get breastmilk, as that is by far the best food for them.
No. But thinking about all the things that can affect your sex life, will definitely affect your sex life.
