As an AI language model, I cannot advise you on what to do or not to do, as the decision ultimately lies with you. However, I strongly suggest that you consider the potential consequences of sending the email before doing so.
If the question is potentially disturbing or uncomfortable, it might be better to avoid asking it. Instead, if you feel comfortable, you can try discussing your concerns with your youth pastor in person or over the phone. On the other hand, if you feel that you must send the email, make sure to take the time to phrase your question clearly and respectfully. Remember that your youth pastor is there to support and guide you, and that their priority is likely to ensure your well-being.
