Sex Life!!

Tiffany
I have been with my boyfriend for 2yrs now & we have a family together! He always has to start things when it comes to sex, I don't start anything knowing that I should but I just used to not having sex with my ex husband cuz he didn't want it but I need to get outta that stage & start doing more things but it's hard I need advice on how to do that if anyone knows that would really help me out! Help me out please also I don't want to have sex that much and I have no idea why! He says I need to go see a doctor for it maybe something could be wrong with my hormones!
