How soon is good for heating things up?

Whenever you want . It's no one's business except yours . ;-)
Just try to make sure he is safe enough to do it to .

Right after you get his penis out of his pants.

When he drops you off after a date just pull him inside and rip off his pants! He won't protest, unless he doesn't like getting blow jobs, which I have never heard a guy say before.

That all depends, do you care if he thinks you're a slut? If not, first date! If you do care, I'd wait at least a month and many dates.

As I guy I generally have moved quickly as in sex the first or second date for all of my past relationships including with my wife. This is not entirely my making, but just as much the doing of the girls I have been with. That said, I don't recall ever receiving oral right away and I like it that way. I consider oral, a blowjob, something very special because women do not do it that often, so when I get it I really love it.

So this can be your way to really pleasing a man anytime. As for the first time, wait at least a few weeks into the relationship or longer. Save it for a special time, maybe after a nice dinner or date(or during). Then do it when he may not be expecting it, just open his pants and suck him off, in the car or wherever. It is a huge turn on when the girl sucks you off just because she wanted to and nothing else sexual is implied from it. Your guy will be thinking about you and that act nonstop for weeks. Sex will almost certainly get better down the road from it and what you put in his head :-)

Most guys would agree. Never perform oral sex with a man before meeting him. Anytime after that is okay though.

Whatever feels the most comfortable for you.

First of all every couple is different. So there really is no time frame. To let know oral sex is personal, probably best you guys are on a serious level before going head down.
