Does prayer become void as a result of physical contact with men and experiencing pleasure without the emission of prostatic fluid (madhy), and is it obligatory to leave the prayer line if there is a young man one desires?

We previously explained that it is preferable for you to pray in congregation at home. Desire does not invalidate ablution unless something is emitted. Your movement from one row to another during prayer with a slight motion is permissible to ward off desire. However, excessive movement invalidates the prayer and is not permissible. If it were said that you have a dispensation to pray alone, that would be a valid point. We ask Allah for your healing.
