**IAM A MALE SPEAKING MY OPINION**
If your "just friends" with the girl it really doesn't matter, but the way I look at it is reverse the roles. If you want to get your mack on, someone with acne probably has really oily skin, and would you really want that rubbing on your face when your making out with a chick?
Obviously this problem only really affects people with moderate to severe cases of acne, the odd pimple or blemish doesnt really matter. Thats just what my opinion tho. Dont let it get you down because everyone (almost) gets it at some point or another.. Once you start to shave and get facial hairs you then get to worry about razor burn and ingrown hairs!
