In that case, you can do this:
"For a trans man who was born after December 31, 1959, is 26 years of age or older, and is considered male by a government entity (such as your Social Security records, driver's license, or passport, as explained above), he can no longer register with Selective Service, but he can obtain a letter explaining that he was exempt from having registered. In order to get this letter, you must get a form from Selective Service called the "Status Information Letter" or "SIL." This letter can be obtained from the Selective Service web site (www.sss.gov) or by calling 847-688-6888 (TTY: 847-688-2567). There is a section on the form that deals specifically with transsexual status. "
It is what someone else posted from this thread:
