Which is normal. Unless your just loose, even when you have anal sex, its a little bit of having to relax, go a little slow at first, let the muscles expand. So I feel its the same with a neo-vagina. Also when watching porn, I've noticied how sometimes even the cis women have to take it slow and its not until about a minute or two later that the male performer is fully inserted or penetrating her. So I just feel like us as trans women, need to relax, stick to the schedule apply the pressure and give it time. Look at my above post to now, I literally have no problem with 4x times a day, granted Ill be down to 3 in about a week and a half, I just started relaxing and truly making it first priority over everything else. My mind now works, by asking, how does that fit into my dilating schedule, so they get done, and I've developed a system that just works and keeps things moving.
All the best to everyone, it does get better!
