Just got one a few months ago...
Hurt like a MF, real BAD. I'd rather have 10 18-gauge needles stuck in my ass. If you want pain, you got it, although it only lasts for about 10 seconds. Blood everywhere... it takes a while to heal, wearing a sock on your dick helps to keep things clean the first 2 days. I waited 2 weeks before having sex, and occasionally it ends up sore, sometimes for no reason.
You take it out in the first 5 months or so and it heals up within days. It's like wearing shoes all the time. Sometimes its nice to be barefoot and you have to wear your shoes for the first 5 months and typically you have to wear the same pair. 2 more months before I get to change shoes or go barefoot. God I can't wait...
Pee'ing is now quite irritating. If your dressed up, you sit down. If you don't care if you make a mess, lean way in and go for it. Don't wait to pee for a long time or when you get in a rush it ends up all over the place. (Too much pressure behind it)
Sex...? Grrrr. Fucking awesome for both parties once you can do it. For the receiver, it's something akin to having one of those studded cock rings on. For the giver, there just a little bit of something extra going on you can't quite explain.
This Helpful (too graphic)? In the end, in 2 months, it will be great to have it and be able to take it out when I want. For now, it's bearable, but I sure wish I could change my shoes...
