Im interested in sperm donation. I don't have children but did try IVF with an older ex girlfriend and when tested, was told I have excellent quality sperm. I am happy to potentially be involved in the child's life or simply donating sperm. I'm just over 6'1, I'm fit and strong and have no medical issues. I teach kung fu, yoga and ayurveda (traditional Indian medicine) and I also work in computer design.
