Hello. Welcome to hcm.
is sexual transmitted disease most commonly spread by sexual route.
You had shared toys where in your partner used it and later gave it to you. As the toy was filled with her secretions from vagina,it had lot of bacteria with it. So when you used it,those bacteria entered and caused infection in you.
You had infection before but it was cured. But antibodies
wil not be produced in gonorrhoea to protect you from repeat infection,you can get repeated infections if exposed.
I advice you to kindly take treatment and avoid sexual contact with your boyfriend. If you already have,he should also be treated.
