Toothbrush

I trust Tenga, and the thought of a toy that is usable on both sexes interested me. They did not sacrifice quality for the sake of the gimmick, though. I've tried all 4, and I think that the diamond texture is my favorite. The nice thing is that it is relatively friendly to people of smaller sizes as well! It was fun to experiment with each different texture. In my opinion, it doesn't replace a very good onahole, but if you treat it as a mix up for a handjob, or use it as a dual wield, with one hand having one UNI on either your balls or your nipples, and the other being occupied with the main action. The other thing is, you can still feel your hands through it, as it is a relatively thin material, so you can the added bonus of the toy and your hand being able to touch any spots you like touching (i.e. under the tip or directly on the tip)

This is a cheaper toy, but honestly one of my favorites. I wouldn't say this is a good starter, because you'll be spoiled with this as your baseline.

Saw a review that said this is the definitive Blowjob toy and I honestly agree. There are no teeth, so if that's your thing, consider that. Very fun to sing your hips into it and have something to actually grab onto

A good quality lube. Use it very often, other than a cum colored lube (personal fetish)

May just be a personal problem but I have to put in a bit more effort compared to other holes to keep this from popping off of my penis.

things that arent necessarily pros or cons but worth mentioning:

Tight
Definitely made of a thicker material
It's straight up just a blue color, so if you're into more skin color holes, you'll need to just take the L
