Is this normal

So i have been married for almost 2 years now never masterbated in those said 2 years, but here lately since our son was born are sex life has been destroyed and i need a release, so I was in the middle of the act and my husband walks in and catches me, is it normal to be ashamed of myself for pleasuring myself because i an really embarrassed like to the point it makes me depressed!? And i dont know what that has done to our sex life if it has ruined it or if he will see i a d appointment or if i have to continue on this solo ride again 😭😳🙄😐
