I haven't been doing a lot of stretching aside from the
Bathmate, but I will say that it definitely feels like it closes the gap between what you can stretch towards and what you have when erect. I've been using solidly for the last two weeks and I've been hitting a mark above what I used to be able to hit when I first got it. So I think in that regard I've gained .4" by informal measurement. Outside of the
Bathmate, that seems to be the same case when erect. It just feels differently in my hand. Not by a lot to where you'd go "what the fuck?", but enough to where it's noticeable.
I think if nothing else, it definitely improves your erection quality, which might be where some of the gains are coming from. I think if you coupled this with some intense manual stretching, you could get some serious gains because the
Bathmate would be so helpful in keeping it stretched out at such a pull like DLD says.
