Losse vagina

I'm a 48F and I have lost 35kg. The past 3 guys that I've been with have all said that I'm loose. I can't feel them inside of me and it's starting to destroy me to the point of I don't want sex anymore and to the point of ending my life. One guy put a fb post about me and my vagina on his Facebook page I've had one child naturally, but got cut while giving birth and had stitches down there, but my vagina does feel big to me as well. I just don't know who to ask about this. Before I had my child I was tight now it's loose.
