R*ped?

So i’m a male and in 2019 i went to a party with two of my close female friends. We were hanging out with friends and drinking. I got pretty drunk and went in my friends room to lay down. My friends that i came to the party with came in with me. They were kinda all over me and kissing me and stuff, pretty excited about the thought of a threesome. I told them no and i just wanted to rest because i felt nauseous. One of them sat on my lap and started to kiss my neck while the other kinda played with my hair. I tried pushing her off and they thought I was just playing with them. They kept pursuing me and I eventually gave into it. We were 17. That night i had went home and i felt awful. I was dating my girlfriend at the time and I went to the party without her because she was doing school work and she was busy but fine with me going with friends. I had told her that I had cheated on her. I was pretty embarrassed to tell her exactly what happened. I didn’t know what she’d say. I also felt bad because she was going through a lot at the time and I kinda made it worse. We broke up for a while but got back together. I don’t know if this would be rape of not. I think about it a lot and it kinda eats me up inside. Sometimes i can’t sleep. I no longer speak to these girls because my (now wife) wanted me to cut them off or she wouldn’t take me back. I don’t know if i should tell her. I don’t want her to think i’m making it up to cover up my “cheating”.
