"I like to feel my partner when we're having sex."
Tim's girlfriend made the choice to get the NuvaRing, a.k.a. the ring, and he's cool with that; he thinks it's her body, her choice.
For him, the ring is great because it lets him go condom-free and really feel her, but sometimes Tim and his girlfriend can also feel the ring during sex. When that happens they just remove it and put it right back in after. (They checked with her doctor, who said that was ok.) It's not a big deal though, especially when you get worry-free sex without the risk pregnancy.
