Ejaculate early first time than second time, is this normal?

Yes, very normal: If a male has not ejaculated recently, he may be very quick to release semen, which can occur even before intercourse begins. After the initial orgasm, however, sexual response goes into a refractory period, during which an orgasm is not possible. The length of time varies by individual and situation. After multiple orgasms, the seminal tract is depleted of sperm and needs time to produce more.
