I'm with SD. When stress gets high it can really put dampener on things. Is it distressing you that you can't and you want to be able to right now? Or is it just the "why" concerning you? (I can't add more on the T thing since other people have said good things).

And I have no problem talking about this stuff. I've brought up sex stuff with my male T. Nothing too detailed. Well. That's not true. I totally discussed cervical mucus once.
