Watch: When is Too Soon to Have Sex? 

The Lovely is a penis ring worn during intercourse, made of medical silicone, that syncs information to your smartphone. The ring vibrates to keep the blood flowing to the penis and to stimulate your partner. The app allows you to clock your duration, calories burned, positions tried, and how long it took to achieve orgasm. It even makes suggestions for future positions to try. 

"It's a little bulky looking for me," says ER Physician Dr. Travis Stork continuing with concerns about dependency"We've always talked about these items in the bedroom...if you use them too much, you can actually desensitize yourself to just normal everyday passionate sex." 

Dermatologist Dr. Sonia Batra says, "When it gives you these suggestions, you might actually talk to your partner more and it might stimulate that discussion as to what makes you happy and what satisfies you."  Research finds comfort with sexual communication is directly linked to sexual satisfaction.
