For me, because my husband is so good at pleasuring me, I wanted to do something for him to try and make him feel as good as he makes me. So one night I suggested he ejaculate inside me (I'm also on the pill). He loved the idea and afterward told me it was the best, most intense orgasm he's ever had. Without the condom his penis was in direct contact with my vagina, allowing us to enjoy the friction more intimately. His orgasm was also unconstrained by the condom and he said it seemed like he ejaculated more than usual. Since then I have always let my husband shoot his sperm into me. I know it taps into his primal mating urges because, for a man, ejaculating his sperm into a woman's body is so fundamental to being male, and frankly we just shouldn't deny them that. And I know that a great part of being a woman is having your man make passionate love to you and then lovingly accept his sperm as he shoots it deep into your body.
As his wife, I personally feel that if my husband needs to ejaculate inside me to enjoy a truly satisfying orgasm than I should certainly be willing to accept his sperm. How can I deny the love of my life the ultimate pleasure my vagina can provide him? Cumming inside me is something my husband needs as a man and I love making him feel truly "male." So for all those on the fence, please, let you husband really feel like a man and allow him to ejaculate his seed into your body. You both will enjoy it immensely and it will bring you closer.
