I am really up in the air . I really love my partner. I just don't know if I'm wrong for feeling like 50 might be too..old to try. I'm 33. He has a 5 year old ...in..great shape..healthy. ..etc. I never asked him to do a sperm...analysis. .because obgyn..said wait a year. .it's only been 2 mos. HOW OLD IS TOO OLD? I would never leave but I considered ..A donor if he can't after a year. .
