Need help?!?!

Today we went to a festival with some mates, I sat on the bus and my friend started like rubbing my legs and stuff getting close to my underwear, then he got a bit confident and kept touching my dih like maybe (5-9 times the whole night), he just kept saying that heknows its big ect, and kept sneaking touches in and said he wants to touch it. then i lent on a rail and he sort of positionedhimself behind me and we held hands for random bits, he then realised to stop and said i should stop and he didnt touch it again but he was still rubbing my legs

WHAT DOES THIS MEAN?!?!!
