My point was that for a considerable number of trans-identifying males, the primary motivation for their claims of being women begins in sexual arousal from cross-dressing. You can verify this from reading their forums (the r/AskAGP subreddit is also quite an eye-opener), and some have even written books about it.
It's something to keep in mind when considering how far the polite fiction of 'trans women are women' should be taken, especially when it comes to the rights of women to enjoy single-sex spaces.
It often is, look up autogynephilia. Also check out the forums for trans-identifying males (e.g. MtF on Reddit) where they talk about their 'euphoria boners' from wearing clothes designed for women.
There is a considerable sexual component in cross-dressing for many if not most of these people.
