When me and DH were ttc he struggled to keep an erection. Our DD is now 5 months old and last night we tried to have sex for the first time after giving birth. He struggled to get an erection and when he went he got soft after a few seconds. He got abit upset and kept apologising so we stopped trying and we had a cuddle and I reassured him that it's ok and he didn't need to apologise, he then got hard again which was strange but we had sex and it lasted about 5 minutes.
Has anyone got any advice or tips on how to improve this? Or has anyone experienced this?
