Was i trafficked or groomed

I was around 18 my friend was 17, we was speaking to this man who was 42 at the time i think(he was either 41 or 42 but I'm sure he said 42) anyway he used to send me money on Snapchat because I was pretty. so I decided to meet him, we had sex, he gave £100 after we had sex. He'd buy alcohol, drugs such as coke, weed etc(I already smoked weed but never touched coke until I met him for the second time when my friend came with me) it was just us 3 for a few months, my friend wasn't sleeping with him just me each time he'd give me money. He'd take me for meals, buy me some things and give me birthday money etc for my birthday. Anyway eventually he introduced me and my friend to his friend who was around 39. I slept with him and had to sleep with his friend as my friend didn't want to. If I'd say no he'd sort of keep asking or start saying things like he isn't impressed with me and that I'm the better one from my friend and everyone wants me. He also slept with my friend. Then another incident he took us to a stay overnight apartment, and wanted me to suck him off with the curtains open. I did. This attracted the attention of some builders across the street and he went and got 2 of their numbers and after they finished work bought them back to the apartment for me and my friend. These 2 gave him some money and me and my friend slept with them aswell as him . The majority of the time we met after this was with these 2 until he bought 2 of his work friends, one which got mad cause I refused to sleep with him and no matter how much the original man wanted me to I stood my ground and said no, my friend slept with him instead.

Majority of the time I'd have to do things with them because my friend didn't want to, she'd also encourage me. Unless we was in his car there was always atleast 2 other men. When he came to my friends sisters house (her sister knew what was going on and was a coke addict still is to this day) she'd pressure or get angry if I didn't sleep with him because she'd want to get some coke

Eventually when I met him by myself to just speak because I was a bit upset he wanted head again, I said maybe another day to which he started getting angry like he used to but this time he smacked me round the face not twice but 3 times.

I no longer speak to this man my friend sometimes and her sister hardly ever as I have a 2 year old now from a previous abusive relationship after all of that so don't want him to be around her sister and her drugs. I don't do drugs only smoke cannabis as it helps with my depression and anxiety and sleeping problems.

My friend said the other day that we was trafficked. I'm unsure of this can someone tell me what this circumstance was as It takes me a while to realise things by myself for example it took me a year to grasp I was raped at a party despite everyone telling me already.

Hiya thank you for the reply! Could you elaborate more on what being solicited for sex actually means? I've googled it but it doesn't give me a clear clarification sorry x
