On one hand, some people might say that it is disrespectful to show sexual curiosity in anyone, regardless of their gender identity. On the other hand, others might argue that sexual curiosity is natural and that there is nothing wrong with expressing it, even if the person you are expressing it towards is transgender.
There is no right or wrong answer to this question, and it is ultimately up to the individual to decide what they are comfortable with. If you are interested in someone who is transgender, it is important to be respectful and to approach the situation with sensitivity. This means being mindful of their personal boundaries and respecting their right to privacy.
It is also important to remember that not all transgender people are interested in sex or relationships. Just because someone is transgender does not mean that they want to engage in sexual activity. It is important to respect the individual's wishes and not pressure them into anything they are not comfortable with.
If you are respectful and sensitive to the needs of the transgender person, then there is no reason why showing sexual curiosity towards them should be considered disrespectful.
