Sex and feeling abit loose

So i stopped bleeding and its been just over 6 weeks me and my husband started to have sex and it was abit painful but its getting better each time we do it now the problem is i feel like im looser down there and loool even when im gassy and force myself to fart ill actually pee a little and this never used to happen before... i had a easy natural labour just lasted over 3 hours and i only had little cuts inside my vagina that required a little stitching but nothing major i guess im just wondering does this get better over time or do.i specifically have to do things to try and tighten my vagina.. i just feel weird inside..like literally inside myself
