Hello, I'm Natsume. I'm seriously dedicated to sperm donation activities. This time, I've carried out donation using the method of directly ejaculating semen into a woman's vagina. Since two days before ovulation is considered the most fertile period, I carefully track her cycle and coordinate the timing accordingly. I also pay close attention to my physical condition, ensuring I'm fully prepared and capable of ejaculating reliably, carrying out each donation meticulously.
