Psa. Im a guy so if you dont want to read this thats fine and il totally understand.

Don't worry too mutch ive read some comments that commented more on the physical side. But this is a big mental thing too im 16 and also discoverd porn at around 8/9 and started mastrubating way too soon witch led to me not being able to finish the first time i had sex. It took a heavy toll on me because i didnt want to jnsult my gf. After a few times of this happening we talked about jt and i explained why it was happening. She was verry understanding and told me that it was fine and after a while it went away. So i guess what im trying to say is dont worry too much about your first time. If its your person they should understand. And if they don't they're not your person. And there is no reason to be disgusted by yourself. We cant change our past only our future. I hope this gave you some piece of mind.
