Hi Dexxus, Welcome to the forum. To answer your questions

1. yes you can use the same razor that your husband uses to shave his face. Just make sure it is stropped before you use it. and that you have at least washed your legs.

2. Lather in sections, and let the lather sit for a min before you start shaving.

3.I apply the body lotion after I complete my whole shave, I usually get in the tub or shower and rinse off using barely warm water, Pat dry and then apply the lotion.

Hope this information helps
