FC2-PPV-4932576. I provided sperm to Misaki-san, who continues to donate sperm, again today. This time, since there was leeway, I performed a direct vaginal ejaculation and then immediately did a second vaginal ejaculation. I strive to do everything possible to increase the pregnancy rate. If any of you actually active as sperm donors have any tips or practices you follow, I'd be grateful if you could share them in the comments.
