To be honest, it distubs me far more that masturbating with your hand you end up wounded and bleeding regularly. On rare occasions when we have sex my OH can get a small tear to his foreskin, this is not a good thing and puts PIV on hold for a few days until he’s healed. I would recommend, since you have bought lube, that you use it when you masturbate with your hand too to avoid this.
ETA I think, though not owning a penis, have no first hand experience that the strokers are meant to make it feel more like having actual sex with a partner. How do you get on with that? Does it still cause wounds and bleeding?
I would also say, don’t forget that LH have a happiness promise so if you don’t get on with a product you can return it, used, for a refund.
