Apologies if this is my second post, I may have hit send toosoon before.
I think the Tenga Eggs are likely really amazing, but are designed with single use in mind. You *can* clean them and reuse them (LOL my autocorrect changed that to "You can clean and treasure them," which I guess you could do as well), but from what I understand, it doesn't last but 10 uses max, depending on how rough you are on them.
Way more reusable (and from what I've heard from the men in my life, way more fun) is the Tenga Flip Hole. Apparently it is perfectly designed for most male sizes, is reasonably easy to clean (and do keep up on maintenance, it helps it last longer) and from what I've heard far outranks most Fleshlights in the simulation category.
That said, if you are a vibration fan, Fleshlight has some vibrating options that last I knew the Flip Hole lacks. I've heard a well maintained Fleshlight is good for around 150-200 uses, whereas the FlipHole is good for up to 300 with proper maintenance. Another point to consider.
Ultimately is it a matter of your own preferences. If you're not good at cleaning up after use, maybe the Tenga Eggs would be perfect. I believe a set comes with a variety of different stimulation options.
As for P spot stimulation, I think Fun Factory makes a lot of great toys for such enjoyment. Also, look into njoy (a brand that specializes in metal toys)... especially if you are flexible enough or have a partner, I highly(!!!) recommend njoy's Pure Wand. That thing is magic for both G spot and P spot stimulation.
