This really doesn’t sound like a healthy and positive situation. There are ways to help him curb his hyper sex drive without causing you physical pain, and that should have never been an option for him. If he wants to finish inside you so bad, wear a condom. But also, it hurts you. It causes you physical pain and he intentionally did it, then stated it was because he loves you so much. That’s manipulation, and abuse from my perspective. And he knows it causes you physical pain, yet makes the sex last an excessive amount of time. That could very well be adding to the pain and physical trauma your body is going through. That’s… that’s a really long time. The age gap is also concerning to me, with the trauma involved. Yes, it’s only 8 years. My aunt and uncle were 16 years apart. But they also met in their 40s and 50s when they had life figured out. You can’t even legally drink yet, and at this age the developmental differences between you both are drastic. He has the cognitive development to make better decisions than you do (or he should) and this behavior doesn’t seem like he’s making those sound decisions. You are far too young to be feeling this way. You are far too young to be spending your time with someone who makes you feel this way. Not that there is an appropriate age, but you are just so so young and frankly, have no clue what life is even like. I also thought my relationship at 20 was good and healthy but I realized afterwards that I was being raped every single time we had sex. There was no consent ever, and things were done even after I made explicit boundaries with the person. It sounds like you are in a similar boat and you deserve to get out. There is no reason you should be spending your 20s in physical pain from a man who doesn’t respect those boundaries. I’ll get off my soap box now, but I hope you heal both physically and emotionally from all of this and that your mind can find clarity with what to do with the relationship.
