Tips on giving my fiance oral?

This is how you give your love good oral...

make her comfortable about you (which if she's your love and to be your wife you already do)
make her feel sexy about her body ( many, many, many, many compliments about how sexy she is to you)
kiss her nipples, suck them and kiss her lips (FOR AWHILE)
then kiss her stomach (whispher how much she turns you on as you finger her p**** with one or two fingers, no MORE)
then go down to her clit and kiss her clit and look at her (if dark let her know again how f***ing beautiful she is even if you can't see her)
then insert finger into p**** and grab her clit with your lips (NO TEETH PLEASE)...
suck her clit and lick it in same motion and forceful with strong tongue and right in the middle of it - the actual nerve ending is in the middle so keep licking it and not softly as she won't feel it, get her to climax by licking it hard until she cums!

Well if the only problem you're having is you get exhausted and are unable to go that long, you should spend more time getting her worked up so she's already on the brink before you start. start by making out, then rubbing her over her clothes, then take the clothes off, start by just using your hands, then continue from there, after about 30 mins of that, it doesn't take me very long at all.

This is a hard one considering every woman is different in what turns them on! All I can suggest is what works for me. Try alternating between fast and slow tongue action and then gently sucking on her clit. While you are sucking on it, flick the tip with your tongue. Tease gently and slowly (giving you a bit of a break), and then pick it up a bit! Multi-tasking always works for me too. Don't be afraid to use your fingers and hands. Women like to be touched all over usually! Reach up and massage her breasts, caress her body! Try using a well lubed finger on her ass while you are giving her oral.
If all else fails, you can always ask her! I know it might seem awkward, but it might actually work to your benefit! Sometimes, a woman doesn't want to demand things, but if asked, she will be relieved the door is open for her to tell you exactly what she wants!
Good luck!

I don't like to receive oral, I guess is just me, I prefer to give oral instead. I never let anyone give me oral, and I have gave oral only to one man and he is my current boyfriend.

1) Different girls like different things so we can tell you all kinds of crazy techniques but they're useless unless they're ones she likes. Ask.

2) Some people like really intense movements, hard, fast, whatever, some people really don't, especially with girls - it can start to feel boring, too much (believe it or not yes there is such a thing) or just painful. You say you're working to exhaustion - that implies you're going a bit crazy with it. Try being a little slower and softer and teasing her and see if she likes that. It might make you less tired as well.

3) Some people just don't come under certain circumstances. Some won't come by themselves, some won't come with other people, some won't come through sex, some won't through oral, etc. She may just have something like that. In which case, don't be offended.

Well,you could just try asking her.Ask her what she likes and what feels good.Yea,my boyfriend hates going down on me cause he says it's too much work to make me come also.

Maybe if she starts on her own instead of finishing, you can be the one to make her come. That way you won't get tired if you can pick things up after a few minutes.

ok, I'm not telling you to go do this, I'm only suggesting. you might not like it, I didn't like it either for the first week, it gets some getting used to, but get your tongue pierced. After about a month, when your allowed to give oral with it, it will get her off in about 5 minutes, or it does my girlfriend. learn how to use it, practice with it, you will get the hang of it, trust me. this worked for me, but it doesn't work for everyone

My ex loved it when I would kiss her clit and finger her at the same time. That would get her to come in about half the time it would have took by just fingering her or giving her oral. Yea but make sure add a little romance to set the mood. Sometimes women can't come if there mind is elsewhere or they're stressed about something.

"She Comes First" by Ian Kerner (Amazon link ) has earned itself a permanent place on my Kindle. :) Definitely opened my eyes to what was possible!

bend her over do it from behind ;)
try something more... animalistic... I guess would be a good word...
make it spontaneous and vigorous and when your tired... just push through..
if you want it that bad... you can make it happen

Try placing her at the edge of a bed or chair so that you can eat her without craning your neck.

Multiple points of stimulation are you friend and make orgasm more likely:

Some internal stimulation does wonders if done fairly gently. A firm press on the g-spot helps as does stroking on the distal side of the cervix (it's a badly ignored spot). Lube is a must in these cases.

Anal play works very well. I prefer to lube up the pad of my thumb and do surface stimulation and shallow penetration of the ass. On most of my lovers, it works like voodoo magic.

Some clothes pins on the aurora can help if she likes heavier stimulation (the nipples work too but I like to leave the tips open for random stroking).

Blindfolds and bondage can help if she was raised in a sexually restrictive environment and feels guilty about sexual pleasure.

Finally, you might simply be exhausting her. Try running her up to the edge and then stopping dead for 15 seconds. This allows the nerves to refresh and get back to feeling the stimulation. You can make a game of it, bringing her to the edge of orgasm and backing off. It will eventually driver her crazy or roll her into orgasm. Both are good outcomes.
