Wrong message ?

I have this friend that I recently smoke weed with, he’s cool and all but I think I may have accidentally gave him the wrong message 😕 I view him just as a friend

Where I think I messed up was on Halloween when we got high and drunk and (although I vaguely remember) I showed him my boobs... we’ve hung out a few days after and when we’d laugh he’d touch my arms and I swear he had a full boner when we hugged 😨... I feel he thinks I’d wanna have sex with him but I don’t ...

again he’s cool and he’s friendly and funny but the only prob is how he thinks he has a chance...
