We Are Engaged, But He Doesn’t Last In Bed

I am a lady of 25 years of age and I am in my final year. I am dating a man who loves me so much and treats me like a queen. Recently, he took me to his parents, proposed to me and I said yes. Last two weeks, he confessed to me that he has premature ejaculation and he also said that was the reason he has been denying me of s*x and postponing it till we get married. I am scared of this, should I leave him for another man who would be able o fulfill my s*xual desire? Thanks
