It took a long time for me to trust my T, but when the trust is there, you will be able to discuss this. I had to start with e-mailing thoughts on this topic to her; could you e-mail your T or write a letter and hand it to her? I am a virgin still, but my first sexual encounter was a sexual assault where I was terrified for my safety, only a few weeks after my first kiss ever (I'm in my early 20's, so you can see that the assault was rather unfamiliar to me even from just the literal standpoint of what he was doing to me/making me do to him). When I tried to have sex with a bf later, I had a panic attack and a whole slew of other reactions. It took me months after the assault to even mention that, hey, by the way, I am a virgin so there's that added element. It took months more to explain the after effect that led to my breakup. It's still an uncomfortable subject for me, but by slowly building trust with her and telling her what I need for that trust, I finally could just say anything to her (and I do - sometimes still in e-mail, though, if it is super personal). For me, trust meant asking for more information about who she is and learning about her family, history, etc. in order to feel more at ease with her. It will become easier for you, too. Just stick with it.
