"It's kind of a little more streamlined."
Justin and his girlfriend have been together for two and a half years.
In the beginning, they were cautious about STIs and pregnancy, so they used condoms to protect against both. Now, as an exclusive couple with a clean bill of health, they use a diaphragm and go condom-free. (Except when she's ovulating; that's when they double up because women are more susceptible to getting pregnant around the time of ovulation.)
In the heat of the moment -- if his girlfriend hasn't already inserted it -- Justin admits that a diaphragm does require a certain level of accountability because they have to stop and put it in. But he also says the extra sensation from not having to wear condom is a very worthwhile perk.
