Sex problems HELP

Idk what’s wrong with me but it’s hard for me to have sex with my hubby because it hurts so bad! I know all these woman who just do it and I wish that can happen to me. I also feel like I’m not pleasing my husband enough because of this. Once he tries to go in it’s so painful and than I tell him to go slow and he does and even when he is fully in I always start crying from pain. Has this happen to anyone else?☹️😭
