Well one thing that should be emphasized...
don't force her to give you a blow job. If you keep bugging her about it she's either going to get fed up with you, or if she does do it, you'll be more or less using her as a playtoy and she won't even really want to do it.
The bottom line is not to make her go against her will - some girls enjoy or don't mind giving fellatio, while others can't stand it. One of my girl friends was what you could call a "bad girl", but she refused to give any guy oral sex - I don't know why; she has her reasons.
But if you are so desperately intent on receiving oral sex, there's a couple of methods I might suggest:
1. Try giving her oral sex, if you haven't already. If you're antsy about stds or the taste/smell, use a dental dam or plastic wrap or something to block it out.
2. Reverse psychology - quit imploring her to suck on your rod. She might start to miss your pleads and maybe she'll give it a shot.

Now in the event she lets ya walk all over her

, be sure to do things her way the first [few] time(s)...If she wants you to wear a condom, then let her. But if she starts doing stuff like gnawing on you or continuing to perform uncomfortable motions on you when you say you don't like it or it hurts, etc.
Of course, if there is any risk of stds from either of you, a condom would be a wise thing to use. But if the relationship is monogamous, or you've both tested negative for any stds, then you don't absolutely need one.
