I gave birth 6 months ago and am breastfeeding. does any of these contribute to me having no sex drive at all? is it hormones or just me?

Me too. Well, think highly it's cos you are tired taking care of yr kids. Also, for some, they have foebia about having another so soon. There are many other factors that may lead to such. You are not alone. Don't worry about it. This is quite common after delivery. Some people takes up to even a year before resuming their sex life.
