They really don't hurt like they look. If you like moderate pinching I would say these would be great! Having the adjustment is such a plus. If you just want a little stimualtion you can have it or with just a few turns you can have more.
to be honest, some women dont have as many pain receptors there so it isn't as painful, other women like to have a bit of pressure so the adjustable ones are perfect. and lastly, some women want the pain, it gives them better orgasms and lets them feed their masochism side while their partner feeds from the sadism side. i am a bit of a masochist. i have a partner who is a bit of a sadist, but we aren't to the extremes... i like pain to an extent and he gets worried if i tear up, even though he is still hard... and sometimes my tears makes him hotter... so if you like light pressure this is fine, even for those who like rough can enjoy it. i cant say im a pro, but it took lots of trust in my love to get to the point i am now... so, only try if you are willing and never force yourself. it can make something good really bad
