Will getting out more help?

So I went to the barber shop today to get my hair cut. This new girl who is around my age (early 20s) was the one who was cutting my hair. I couldn't really talk to her just about how the day was because I was to busy focusing on fighting my erection and trying as hard as I could to look like nothing is happening. The only thing I said akwardly was "so how long you been cutting hair for" she said about a year and said she went to school for 2 and conversation ended in awkwardness. I am really pissed off at myself how I allowed my hermit life style over the years to control me. I can't even talk to a pretty girl just about how the day is going without fighting an erection.
