am i over reacting??

i just started my new job last monday, a guy i went to high school with recognized me and asked for my number. he paid for my breakfast and dinner after work. we basically spent 3 days in a row together and he paid for my meals on all those days. he says he really likes me but he’s veryy clingy. he’s been begging to see me when i told him i need space. we work in a warehouse and he told almost our whole belt that we “talk”... now this is preventing other males from even saying hello to me because they think im his girl and i made it clear to him that im not. i wanted to keep me options open but he made it difficult. he’s also always telling me what i need to do. “you need to wash your hands” (we’re constantly touching boxes) , “you need a cold towel” ( i was sweating at work), “you need to wash your mask” (wasnt dirty). he really sweet honestly but i cant see myself being happy with him. he gets turned on by the most smallest things and he moans very weird and i dont like it. he’s also very small down there and i just cant see myself ever enjoying having sex with him.. ik it sounds bad.. but am i wrong for not wanting to pursue anything future with him? i only been knowing him for a week but i’d feel bad that he spent all that money on me now i wanna end it..
