I masterbauted and wiped it off with toilet paper an hour before i started fingering my girlfriend, i washed my hands with soap and water for like 10 seconds before fingering her,is there any chance that she may be pregnant? how likely is it?

Pregnancy risk.: That situation does not present a risk for pregnancy.

Agree with Dr. F: From what you described, the risk of pregnancy is near nil. However, both of you could still transmit STDs to each other. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!
