Listen don't be hard on yourself. Balls are an insane thing.
I myself own two and barely know what the hell to do with them. As idiosyncratic as dudes are with their wang, they are double when it comes to the nuts. That being said, there are two pillars you should know and breathe when handing the balls. The first being a cornerstone for both Doctors and ball handlers: Do no harm. If you don't know what to do, do nothing at all. A scrotum is stupid sensitive. All those '80's movies with guys getting socked in the nuts come from a place of truth.
Squeeze, press, poke or pull even a smidge too rough and the nuts will let you hear it. Rather, they'll let their owner hear it and you (the lady) will be subject to man's primal survival mode. You'll be choked out, thrown off the bed, or hand slapped so hard you'll think you're in grammar school in the 18th century.
Second, ASK your man what feels good. You can't expect to navigate a man's nutsack blind. That's like asking an Amish kid how to get to Brownsville, Brooklyn from Central Park. They need a map, a gentle guide and a willingness to fail. One size does not fit all when it comes to hand jobs and especially ball play.
So there's your answer. I'm sorry it's not more specific, but that's the point: it's on a nut by nut basis. What's lovely is that you've shown you have the interest and gumption to incorporate your man's scrotum during sex play. You're forward thinking, and I'm sure in no time the four of you will have a ball.
Clever, funny, mostly grammatically correct and most importantly... full of solid advice :)
( just a side note here im going to be very detailed here with my advice.)
Well let's see here first of ask your man if he does like his balls played with.
Some guys don't care for it and others love it. Start off off slowly with licking and lightly taking one of the nuts into your mouth no sucking and slowly almost like a your giving head but in a very soft mannor. If he likes what you are doing continue but this time add a little sucking pressure, while you are doing this have one of your hands stroking his member. Switch from one to the other, the gentler you the better if he wants it harder ask him or he will tell you. Tell him to voice what he likes to you so you know what he is liking and what he doesn't. If he's the kind who doesn't like it no worries I have found an excelent double hand job that I will also share with you :)
Double hand job: okay with this you are going to need a good amount of lube one that is more on the expensive side one that doesnt dry out or wind up sticky after a few strokes, but KY will work just as well, just need to re-lube more often is all.
To start off put lube on his member and both your hands, now put both hands around his cock and interlock your fingers. His member should go in the spot where your pointer finger and thumb make a hole. Now while stroking him you are going to not only run both hands up and down his shaft but also squeeze and release as doing so. With your thumbs and pointer fingers you are able to play with his head. It's a great way to stimulate everywhere a man is sensitive all at one time. My boyfriend was blown out of the water and amazed with my technique! You are easily able to increase speed and pressure while keeping a steady pace! I hope this has helped. :) I hope I wasn't too graphic here. Lol
Excellent tips, I do pretty much the same, and it drives my boyfriend mad!!
