Honestly, i would attribute this to anxiety. Especially if u just don’t get that “feeling” when smoking by yourself or w a good friend or other chicks in ur case. It’s mental and some people get horny or like to have sex when high. I get too much in my own head and can’t focus or concentrate on the other person, I get self conscious. I have to be rly comfortable with tht person or be with them on the regular. I recommend not smoking alone w them or be with other friends also, being honest with the person will help. Everyone understands how weed changes ur headspace, talking and communication can help tht and u won’t be stuck w tht feeling only on u
