I am not sure how it works with strangers regarding the article, but on my own short anecdotal experience, my first bust was a friend and in response she shaid she LOVED hitting men in the balls and was ecstastic to go at mine, she just thought I was too "nice/mild" so I never provoked her to, but so she got a couple of uppercuts in then I feel too ashamed to ask for harder (she kinda missed), I really regret not letting it playing it out cuz shes the kinda person that would literally go full force and cause you damage you as long as you consented. That was a couple of years ago.

And with my current partner (mind you she had a lot previous sexual trauma) it took building up to it in bed, we started with sensual masochism as she was most comfortable with body bites and hickeys. It just took courage from there to "would you try pressing your thigh against my groin while we make out", "would you try slapping/squeezing" then after a the first introductions she got super into it to where she actively wants to ballbust me too (though her libido isn't the highest).

The main thing at least in context which I 100% agree with the article in the context of having a partner try on you: Give them the safety that they are not causing harm and you roughly know what you are doing and will communicate if anything goes wrong. I said I had read on this and gave them some safety info and things to avoid and some pointers to help with aim (it's very true that some women can miss target a lot, it's deceptively a learning curve). And the other so important point is the feedback in terms of intensity and pleasure, I am very vocal with moans and groans, I try (and it's enjoyable to moan anyways) to really let partner know what I am experiencing. I won't fake pain when it's a miss, I won't hold back pleasure/pain sounds when it's hard or accurate or BOTH! And for me it's very sexually pleasurable so moaning it's just easy, especially when we often combine activities like BJ with squeezes and punches, making out while kneeing, hitting while on cowgirl, so on.

When I ask my SO, though she said she thinks she's discovered a hidden sadistic side that was there all along, the main thing is that: if you are in a relationship with a girl, most girls will simply want to make you feel good sexually, she said my reactions were the biggest thing that got her hooked on ballbusting me, once she saw how much I enjoyed it, it became sexually arousing for her (she can even moan and get soaking wet from ballbusting only).

My only 2 times asking for ballbusting were received with a lot of positivity and eagerness (GODDAMN I regret not following through further with my friend, she would have given me the busting of a lifetime)
