Hi there, I am new to Penis Enlargement too. I tend to have a bath every day and I like it hot, so this is when I am doing my excercises. I have a soak for 5 mins then stand up and dry penis before lubing up with petroleum jelly which I find works beautifully. Then when I've finished I sit back down and have another 5 min soak. Another benefit of using petroleum jelly I have found is that my penis stays more or less permanently moisturised which has to help reduce risk of bruising etc, I assume anyway.
Good luck, man
