An amazing amount of women do not orgasm with their man. I want to say I remember a recent Playboy article saying better than 50% although i can't find the article and there are a ton of them on the net that list 75% etc. I'm sure if you ask those men they probably all think their ladies are cumming so something in certainly missing in the communication. Those of you that use toys with their wives / girls are likely some of the few that are actually in fulfilling sexual relationships and kudos to you.
Whatever you do as a man, make sure you are taking care of your woman. If you have to ask if she came she probably didn't and if you rely on the old in and out for x length of time to get her to cum realize that she might not be getting there. Plenty of woman simply aren't wired to climax with only insertion. Some can cum that way but only after getting fired up with an orgasm or two from oral first. Others it just won't happen that way regardless of how long or hard you plug away.Every woman is different, very different.
Getting a woman off isn't exactly easy compared to say getting yourself off. Want to see? Take one finger and rub your dick with just that finger. Wet if if you want that is ok. That is all you use and try and cum that way. Not so easy is it? You still have a shit load more to work with than she does since most of your gear is still on the outside of your body. Also keep in mind that if you are a douche bag to her all week or in general not emotionally fulfilling don't expect miracles. Woman are emotional creatures and emotion is a big part of sex for many of them. You need to fill that gas tank or you aren't going to get far.
Anyways, don't be a putz and assume she is getting there. We are all conditioned to moan and whatever from the shitty production porn we've watched. Most of you are not getting her there that is a fact. Fix it before someone else does it for you.
I'd suggest starting with masturbation and making sure she knows how to get herself off. You'd be surprised how many woman have NEVER had an orgasm or are uncomfortable with trying.
Start slow, always warm her up, they aren't as visual as we are and require emotional input to stoke the fire.
Oral is always good. Several methods, looks them up and try them. Gentle and keep things out of her vagina until she is warmed up. Don't over stimulate one area spread the love around. Ears, lips, neck, breasts, nips, belly, thighs, labia, vagina, clit etc.. Keep her guessing don't just work your way down there.
Work her up and get her cumming. If she isn't sensitive enough that day then break out some toys and try different types and settings. She'll find one she likes. Once she figures out the muscles she'll be on her way to being a cumming machine and you'll be the one that got her there.
