For any single women out there, is it natural not to want another man after your first lover?

My ex-husband gave me the best sense of fulfillment back then and also a beautiful son who I can concentrate all my energies on. I'm 37 now and don't feel cravings for a male. Even though he treated me badly and left soon before my baby was born. Maybe I've lost trust in all men. They only need us to stick their thing inside and betrayal is their true character.
