I suggest delete this post as this is a public forum and if the alleged somehow gets a hold of your concerns, he or his friends will report the incidence (whether you get suspended or not) to your new school in Fall and get you in trouble.
Maybe You can seek advice maybe from some members privately.
Just my 2 cents.
However, since it involves sexual harassment , you should be fine . Just make sure you state that. Don’t worry too much. Stick to your story.
