Bondage and lingerie to get arroused

I see a lot of movies with guys having their cock and balls bound, wearing a thong and/or other lingerie while playing with their Aneros or other dildo. I find that watching and dressing up myself is very hot and use this during my own sessions. I feel submissive at that point.

My questions for this group:

1. My cock and balls are bound tight and this is a very pleasant feeling. But doesn’t this counteract my goal of a prostate orgasm, in which touching my cock shifts my focus? and do you guys also have this need?
2. A thong and other lingerie is hot, but also seems unnecessary or maybe excessive to achieve my goal. What do you guys think? Is this normal (trying to figure out my preferences).
