One suggestion is to spray your clothing. People say that there is a possibility of staining with the colognes that have color but I've sprayed my white shirts with every color cologne and never seen a stain.
Another suggestion is to put lotion on your body before you apply. I have heard that helps a little but I don't really know how. I've tried it and havn't noticed much of a difference but give it a shot.
Welcome by the way!
Those are my suggestions. If a cologne is weak then you mostly just have to deal with it...
