One of the things that occurred to me before I did anything with a dog, was "you can't unfuck a dog".
That being said, I took things slowly, a little at a time and gave myself and the dog a couple of days in between things to let things soak in and process in my mind.
It's been a long time since I went "all the way", and no regrets ever.
Whatever you do, realize that there is a difference between right and wrong for you and where the rest of the world is concerned. What I mean by that is don't let the world tell you what's right or wrong for you. Decide that for yourself.
My right and wrong is decided by any negative impact on anyone or anything involved would be considered wrong.
Anyone not involved does not get a say. Of course parents catching something like this would try to claim a negative impact on themselves, but as far as I'm concerned, the only impact is in their heads from knowing. therefore don't let them know..
Best of luck to you, and I tend to agree with the other person that said it would be better than some street stranger..
