I ask this question two years ago and this is what I have learned

No sex toy company really replicate tela vaginal sex it's just impossible but some fleshlight sleeve come close if you take out the self lubrication and warmness of a real vagina.

Base on my research, reading articles in the internet and reviews, comments, base on my own experience and asking veteran flyers in the sub who has a huge collection and have tried all the sleeves fleshlight has to offer

The most realistic and more pussy like would be

Mini Lotus - most pussy like in realism

Wonder Wave - feels realistic best recommended for girthier and below average guys

This is also a budget friendly fleshlight if your in a budget.

If you want something is the fleshlight girl series who has orifice molded from a porn start the most realistic would be

Eden

True Lust

Lust

Silk - loose fl sleeve

But with it come to realism most of the guys in the sun like Eden and True Lust the most, base on the reviews I read and my own experience.

For realistic and med intense the best ones are

Beyond

Fuego

Ethereal

Stellar

Cream

Majority of the married men in the sub like beyond the most for the realism mid intense category because as they say in the comment it remind them of the sex there having with there wife. The second most realistic in the list would be Fuego it's just also really depends which one your like the most
