Ask before you suck! I blame the porn industry for the ball sucking thing, but I personally detest it! And that comes from a guy that do not have a problem with deserved CBT here and there... Reminds me of Reddit post of sexual-oops where girl's first boyfriend liked to have balls hard squeezed during after the ejaculation, and she found hard time with her next BF that not everyone likes to have family jewels turned into the diamonds with firm squeeze. 😃
