Best PE to do before sex?

I was wondering a simple question what Penis Enlargement excercise would increase blood flow that you can do right before sex lets say 30 mins before sex ? I thought jelqing would be it but i feel to jelq you need to be calm and collective. How about balloning ? or is there any other Penis Enlargement that will work ?

A few people elsewhere mentioned using the Bathmate + viagra before sex. I think a Bathmate/manual combo such as DLD girth blasters with viagra in the mix would give solid gains for before sex. any thoughts?

Bathmate before sex would be the best move, you could gain a temporary inch!

This is the thread with infor that

It depends on what you want. Bathmate might be fine if you want a temp pump, but I've found that 5 mins wet flaccid jelq about 5-10 minutes before sex really helps in the control department.
