Last summer I was sexually assaulted by my best friend. He had made physical advances that I told him I was uncomfortable with.
One night at a music festival, we got drunk. He went to sleep in his sleeping bag long before I did. When I went to my sleeping bag, he rolled over and started trying to engage me physically (I don't think he was still drunk). Eventually, he was fingering me. I was on my period, had a tampon in, and it was very painful. I just closed my eyes as tight as I could and cried a little bit. I've read that any penetration counts as rape, but I've also read that "only" intercourse and oral sex count as rape.
Was what happened to me rape or assault?
For months after he continued to make physical advances and emotionally abused me until I was able to completely get him cut out from my life (with the help of my incredible best friend)
