If you don't wanna risk an irl relationship, then it might be better to look for someone else. That way, if it ends between you 2 in a bad way, it won't be quite so awkward.
Depends where you live? Also depends on the search tools you use (age, distance from you) I came across like 3 or 4 people I knew but that's out of the 100+ guys I saw on there
HaliFord create a fake FB with no pics, you can attempt to see if you see anyone you know there :p even then remember people join like everyday, if it's something you're not comfortable with yet it's best to wait
