You are only 20 so you are barely outta ur teen yrs urself. But pre pubescent to young teens...you are bordering on kiddie porn there..that I would DEF. AVOID. But older teens like 16- your age...is not abnormal they are still in ur age range... but obviously don't engage with anyone under 18 cuz you could get slapped with statutory rape charges. I am a woman but I think that regardless of gender or sexual orientation it is very common esp with porn to fantasize about that feeling or age of coming into physical sexuality... porn obviously when over viewed can desensitized and confuse our rational minds. But in moderation, gay, hetro, lesb, bi porn there are a lot of actors that are18+ that "play" younger...and I think as long as it does not become a fixation where you fail to mature naturally in your sexual desires...it serves in way like a memory fantasy almost. You are still very young, but I think regardless of age,we all have times where we want to relive or recapture periods of our youth vicariously. And there's nothing wrong with that as long as it's all legal and consensual. But maybe try to give the porn a bit of a break for a while if you feel like you are getting stuck. Hope this helps. Be safe.
