"Using two condoms at the same time-either two male condoms or a male and female condom- is not a good idea as the friction may result in one or both of the condoms tearing. If you want to take extra precautions against pregnancy when having sex, and are concerned about the possibility of a condom breaking it is better to use another form of contraception. For example, using a contraceptive pill, patch, vaginal ring or IUS as well as a condom will ensure that you both have double protection against pregnancy as well as protection against STIs."
"There’s almost no risk of pregnancy from fingering or hand jobs. If a person has dirty hands and touches another person’s genitals, they can spread germs or bacteria. It’s possible, but not likely, to spread a sexually transmitted disease (STD) this way. However, there’s a very small chance of starting a pregnancy if semen gets on one partner’s finger and that finger is put immediately into the vagina. It’s a good idea to wash hands before and after any sexual contact."
