Cool well i just started wearing every night. I was doing something around the same lines but i was using diapers once a month now i want o try to get in to it good now like every week at bead time. But that is another topic for another form
I was right where you are. When I first started wearing I would "get happy" and it would make it difficult to go because I would be pointing north. Now that I have been wearing regularly for the past few years I don't "get happy" nearly as often. Just hang in there friend and you'll be just fine.
Mine is partially *filled* the whole time I'm wearing a goodnite, probably because its so tight. I like to wear my plastic pants too and then its really *filled* up, but I'm more of a DL then an AB so I don't really mind. However to get it to go down I just calm my self down, think of other things that don't provoke arousal.
years ago I had this issue, and I would simply relax and give it time. It won't stay like that forever. (and if it does... that's not good) When you've been distracted for awhile and your thoughts return to your padding, you should have a little time to "rearrange" yourself before your body can react again. That's what I would do, just be patient with it, you won't stay hard forever.
Nowadays I can usually keep things where they belong. Problems from time to time but they never last too long.
