Hi guys

I’m new to this and read a couple of post but I’m confused about few things. I’m currently on : https://fleshassist.com/en/advisor

So let’s not waste time on the death grip syndrome subject. But what criteria am I looking for my objective ?

Do I need low or high intensity ? Low or high tightness ? Etc what are the criteria I need to find the one best suited to me.

To make it short I masturbate for 2-4 hours with a cock ring and Vaseline. But with my gf she complained about lasting too long (more than an hour) and I just can’t cum with her unless I use my hand to finish. Which I don’t complain but she does.

So what type of flesh light are recommended in term of design ?

Thank you !!!
