With the trans girls you've seen more than once, what's the greatest difference in cock size and hard on factor? I'm only asking how much bigger or smaller their cock was and their ability to get it up and keep it up on and off hormones and specific related topics.  

Obvious thoughts; how can you be sure a provider is on or off them? Do they lie and say their not on them, yes they do. Also, this is mainly applicable to girls who exclusively top, are vers tops and the truly versatile girls. Other thoughts; how much does age play into it, weight loss and weight gain and how many might be taking viagra, cialis or similar type meds and products?

This year I've re-visited many providers I saw 5-15 years ago, all tops and vers top girls. Some had gained a bit of weight lost some cock length due to lower torso body fat. Some girls weren't as hard as they were when they were younger. Both of these things make sense and have affected me also. What did not make sense, some of the girls were bigger and much harder than I remember even though they're older. A few girls said they no longer took hormones, others said they just started taking them. Some said they take only oral hormones, some say shots some said time released injections.  

Generally speaking, if they were on them they didn't get as hard or stay hard as long as you would think. Some were 10%-20% smaller or larger on or off them which makes sense. What makes zero sense is a few of them gained 10%-20% in size are still rock hard with stamina and said they've always been on them. So, while some of it makes sense, I'm trying to gain a better understanding of how others have fluctuations of size and performance and the simple thought they're on or off hormones might not be a factor? Are trans women getting more into viagra, enlargement procedures etc.?
