My Trans friend is constantly horny and I'm freaked out.

So I'm trans fem/non binary, go by she/they and have a trans friend (Mtf). She's really lovely and she came to my defense when I was arguing with my dad about the current state of the US and how it's effecting us trans women in the UK too, she even took the time to privately message him which I appreciate but felt awkward because she was getting too involved. Not long after we had a few conversations, normal stuff but recently every time I ask her how she feels she says shes horny... And when I try to change the subject or talk about anything else she just gives shallow responses and isn't very talkative. I feel very concerned about her because I don't want to form a shallow relationship with someone who's constantly horny and want's to fuck me... Am I wrong to think that it's also a really bad look especially for a trans woman to be constantly horny? Is it a red flag? Because there is just too much negative perceptions about us trans women that were nothing but porn or masturbation addicts and this thing with her being horny all the time just seems like it's adding more fuel to that negative perception/stereotype. I'm gonna see how things go and see if she has more to her than just being horny but if it's just more of the same what should I do?

UPDATE:

The comments have been very helpful thank you. However, I did set boundaries but it didn't seem to work much because she still told me she's horny and I didn't even ask her how she feels this time. Still doesn't say much outside of that though and is just more shallow communication. She even asked if it was ok to be horny which I responded saying "In your own time, i really don't need to know 247" (I'm just realizing how blunt that is) She said "sorry" to which I responded "Let me just set some boundaries, I'm demisexual so which means I don't get horny or sexual like most people, I need a strong emotional attachment for that... It takes time. I can talk about it sometimes but if it's gonna be constant sexual conversations then it will just push me away because to me I want more meaningful friendships, not ones that are shallow (for a lack of a better term) All I can say is imagine if someone a straight dude being interested in a girl who's a lesbian but kept talking about straight sex or even came on the lesbian constantly, that would be overstepping the bounds of his sexuality and infringing on her sexuality. That's what it's for me as demi/pansexual when someone wants to talk about sexual stuff, constantly tells me they are horny etc. I'm just not interested."

Was this the way to handle it or have I made things worse?
