I'm a trans man, so as much as I appreciate your belittling I have my own experiments with being treated like someone's 'first'/experiment/people finding us to be a kink / people only being okay with it because my body appears to be a Cis woman's. And I'm 30 years old so frankly I have quite a few of those types of experiences and have met people like you have met. In the end it comes down to communication, finding healthy boundaries for yourself, your values, and learning from your mistakes (ie. This was a bad experience for me, and no matter how good it seemed at the time I'm not going to do that again with someone who does blank.) Have a great day :)
