Even though I am leaning towards getting a meta, I would still love the ability to penetrate my partners, at least in a way that is an improvement on what I have now. Was thinking of a
penis sleeve (link NSFW), but with a smaller hollow portion for a meta-sized penis? I am not sure whether there is anything on the market that would work, or else developing one myself. One issue I predict is keeping it adhered without a harness - not sure whether a sleeve can adhere to even a large meta the same way a biological penis can.
Another idea, which would involve some R&D, would be a suction mechanism on the clitoris/penis embedded in the shaft. I think there was a dildo with a similar concept, marketed as a '->-bleeped-<-' dildo, but it is unfortunately discontinued.
Do you guys think this is doable?
