If your husband loves it when you touch his taint, the smooth area between his testicles and his anus, then try this with him. It is actually a position to put him in which results in a higher degree of sensitivity in that area. A position he gets in for a hand job essentially. How you position yourself can vary.
Your husband should get on his hands and knees with his legs spread apart about a foot. Then he needs to lower his upper body at whatever degree is comfortable. This will cause gravity to draw his sack away from its usual position resulting in the skin tightening over his taint. You can then give his taint attention as well as his penis and anus at whatever level you are both comfortable with. It is very effective stimulation.
You can position yourself behind him which allows you to access the area easily and his head can be lowered, resting on a pillow. Another option is for you to being laying on your back with him resting his head on your stomach and you can reach around and stroke his taint that way.
I do not mean to use the following picture disrespectfully since the man is praying, but it is the most modest picture I could find that accurately portrays the position I am describing.
So you can start him off like this and then having him lower or raise his backside depending on what feels good.
If you haven’t tried this, give it a try soon. See if it is something your husband enjoys.
