My gf and I live together. Im in the fortunate situation in that I start work two hours later than her. I wake up with her, and do my Penis Enlargement before I myself go to work. I don't do anything on the weekends as I literally have zero time apart from her and haven't spoken to her about Penis Enlargement yet.
As you probably know - unless you're comfortable explaining it to her, there's not many ways around it. Try and get your Penis Enlargement time in during the moments your apart.
How often do you stay over? And when you do, do you really think you'd have time to practice Penis Enlargement?
