Any advice on how to improve my oral stamina with my wife? I get pretty shocking tongue aches and cramps. The first orgasm she ever had was from my mouth on our honeymoon, so I know I can make it work, but we’ve had long periods without oral and I feel we’re rediscovering it! I generally approach her from a 69-type position I.e. upside-down at some point during most of our sessions these days but can very rarely get her to orgasm. On a related note my wife has shown zero interest in reciprocating in spite of my very occasional suggestions. Any ideas what might nudge her to give it a try? I’m pretty good on the hygiene side before anyone suggests a shower… thanks all!
As to your first question, you may be too far away from your target. If you are having to extend your tongue to reach her sweet spots, that can cause fatigue and cramping. Your mouth and lips should be on her mound so your tongue doesn't have to reach at all.
If you really want to get her going lick her ass ( if it’s clean) first, it’s unexpected and it will turn her on, some rimming and maybe a little tongue insertion. Then flip her on her back, spread he lips apart and suck on her clit like your trying to suck it off. It’s not all about the tongue, kissing, sucking all works, my tongue used to get tired too but then I discovered I can use my lips and my entire mouth to get them off.
You improve your oral stamina by... eating her more. Not only does practice make perfect but it also makes you work on being able to eat her longer and starts to reduce the stresses on the mouth, tongue and jaws. Those are all muscles or connected to muscles that, like other muscles, have to be exercised to get the best performance out of them. I'm not going to try to tell you how to eat your wife - but I will tell you to eat her more often (if she's willing) and push yourself to increase your oral stamina.
Practice and practice and more practice is the only true way you will build up stamina. I will be called weird here but I was very awkward when I was in my early 20s and used a ton of sex toys, mainly blowup dolls. I used them often for sex and also had some with realistic vaginas that I practiced oral on like I saw in some porno movies. And it actually made a ton of difference as I when I was doing it regularly I could go well over an hour without much soreness. I had to come up for air, but wasn’t sore.
I like to be on the floor beside the bed with her bottom right at the edge. I can put her feet on my shoulders and spread her legs. Easy to get at her pussy and I don't get tired as easy. I will say that once you both find the best way to lick her and make her cum, it happens quickly, leaving plenty of stamina for other things or a second round of pussy licking.
