guess what. you are normal. that’s the first thing that has to be understood. but really there are a few points here:
1) the point I already made is that as a teenager this is normal for girls and boys to feel there’s a reason why it was made like this is so that people will get married eventually, if this strong feeling wouldn’t exist nobody would ever get married because of the headache involved and the sacrifices and commitment of a family.
2) even though you are normal, many schools are struggling with the fact that the teachers cannot relate to the students. you will have cases where a student has simple questions on hashkofa, or a students has hormones and is attracted to the opposite gender like in your case, and the teacher or school lacks the experience to answer these good questions and tells the student that they are a rasha or bad kid, and they want to kick them out of the school. this leads to a big problem where people think that we do things in judaism without reasoning just because its what frum people do. however we live in a society and generation where blind faith will fail. things need to be explained, because the world out there is getting very enticing and if people don’t feel acknowledged and answered and we just do things because that’s what we do for no real reason, that will make our religion look like amish people and can cause many people to go off the right path.
3) another issue is that based on the last 2 points we live in a society right now in judaism in the circles that you are talking about especially where if a person thinks out of the box and sincerely asks questions they will be looked at as an outsider/ rasha. did you ever wonder why for example there’s very little cases of OTD by sefardim, the reason is because by them you are accepted and your questions are answered even if we don’t have the answers all the time but the questions are validated and not frowned on, its because they are much more accepting and not pushing away. by the yeshivish and chasidish circles there are many pros but one big con is that if you ask a question get ready to be an outcast. but rabbi miller’s mehalech was not blind faith at all in fact I heard him say clearly that he was against it. people need to know reasons for why we do things its very important.
now for your case either switch schools to a more open minded yeshivish bias Yaakov ( its not a contradiction) usually in NY you can find that, or just ignore what they say to you in your own school until you graduate and go to a more normal seminary where they address your concerns. don’t talk to boys until you start dating. but there’s nothing really wrong about asking questions. our whole torah is about asking questions and challenging. that our entire religion. the whole gemara is questions and answers and proofs. so whoever says its wrong to ask is just weird.
