Looking for just the tip are you?

If you are looking to Top the TS then it will be similar to an anal only booking with a cis WG.
If you are looking to Bottom then it will be similar to getting pegged by a cis WG. But just like a cis WG seeing a cis punter you may need to stay aware of when they are and aren't using a condom.
In terms of looking at TS WGs on the various websites, I think they use more filters in their photos than cis WGs. They use it to look more attractive but also to look more feminine. It could be body dysmorphia or just good old fashioned bad business practice. I think you need to look closely at every photo they have (as well as read in detail their description on multiple reviews) if you are looking for a very femme TS WG.
If you are looking to Top a femme TS then pay attention to their height in their bios. They may look femme in their pictures (and hopefully in reality), but if you are 5'8" and they are 5'11" and have 10lbs of muscle on you, they might not feel very femme to you.
