What Is The Best Position For Having A Good Penetration?

Subject: problem penis penetration Me: female, age32 years, height 5 9, weight 105 kg Husband: male, age 37 years, height 5 8, weight 70kg Marriage date: 20 march 2014 We both virgins before marriage. I directed the penis to the hole he tried penetrating but could only penetrate 2cm & then when pushed it bent & hurt. After that it doesn t penetrate even a little. The position we tried was me down & he up. We have tried with & without ky jelly. We are really desperate we wanted our first penetration with a condom as part of experience & then want to do unsecured as we think we are ready for a child. Could you please give tips on a better position & anything else that would make penetration possible Many thanks puja:)
