Need help with sex

Alexandria

So I have been having a little trouble in the sex category lately with my husband. We had our first kid 7 months ago. I think we have had sex like 3 times since then. We share both bigger people (6 ft tall and 250+). I am not ther best on top. I just want to blow his mind. If anyone has tips on bjs or being on top. I am all ears and open to any suggestions.
