Hubby has low T

Hey y'all, I'm new here but just thought I'd throw out a question. First my husband is an amazing man and we work hard to have a successful marriage. But we found out a couple of years ago he has low testosterone. Very strange for an active man in his early twenties. Just wondering if anyone has dealt with this and has any success. He doesn't really care for pills so I try not to push those - but our lack of sex can cause conflicts. Any advice is appreciated. Thanks!
