My girlfriend and I (18 years old) were fooling around sexually and I took my cloths off and she was in her underwear. My penis rubbed against her vagina several times but I did not ejaculate or penetrate. Plus I might have touched my penis while it was wet before pleasuring her vagina. We are scared that she might become pregnant and we can't buy control pills. It's been 2 days since that happened and she's not showing any signs.
