Sex after a hysterectomy

I am worried and apprehensive about having sex after my full hysterectomy I am 6 weeks po , I am seeing someone but we don’t see each other very often. I have read so many different things online and I am worried about having sex for the first time after op How long should I wait ? I’ve always felt a bit of pain when my fella penetrate’s me , but worried it will be more painful. Would it be better to try foreplay first with his fingers I have no idea And advice would be very much appreciated
