Should you give a HJ before I give a BJ?

No, handjobs just desensitize the guy's penis and then the blowjob doesn't feel as good...especially how some girls give a handjob really hard and fast like they are trying to start a fire or something

No, give the hand job while doing the blow job. I find just the mouth boring, I want the stimulation of both together.

yeah it helps gets him ready for the BJ

I'd say it's personal preference on both sides.. like a guy for whatever reason might like hj's more than bjs.. or other way around.. same as you might like giving hj more or bj more..

If you just started out with him or whatever.. maybe hj's first... idk. I'd ask him to finger you... both partners messing with each other at the same time probably would rock... lol

yes keep him begging for more =) muaahahahahhhahha
