Welcome to Susan's, Spartacus!
This site is a great resource for information and support. It's a great way to introduce your SO to Trans-matters, and to help both of you with answering any questions you may have.
I am the SO of a MTF and I can honestly say that joining this site has been one of the best things that I could have done for my relationship with my SO, and for myself in general. Everyone here is so unbelievably kind and beyond supportive.
I look forward to reading more posts from you, and I hope to see your SO around here as well.
Hugs,
Jacquelyn
