I don’t know how to feel

My a few nights ago my gf & I were making out at our buddy’s house and she started kissing my neck then I feel her sucking but I don’t do hickeys on the neck bc I rather not go to work with that. And she knows that so I told her no then she stopped and starts rubbing my neck I closed my eyes bc it felt good and she started sucking on my neck again I pulled away and she rubbed my neck again then started sucking again. at that point I gave in bc it felt so good but when she would start sucking too hard I would push her off by grabbing her neck, I guess that turned her on which only made her worse she pushed her weight against me on the love seat and started to grip my arm a little hard it made me a little uncomfortable because I just felt like she knew that I didn’t want it but knew if she did it I would like it I’m not sure if this was just a dominant move or her over stepping I brought it up the next day and she said I heard you moan “yea” so I feel like that might’ve thrown her off I’m not going to say I didn’t like it but I definitely regretted the hickeys once we we’re done
