Condoms are the most effective form of STI protection, so why use something that’s not shown or proven to be effective, Gittens says.

“The Jiftip probably doesn’t have a good enough seal — viruses and bacteria like HIV, HPV, chlamydia, and gonorrhea are small enough to be able to get inside of the urethra and cause these problems.”

And if you like ~rough~ sex, accidents can happen where microtears open up on the shaft of the penis, providing an opening for STIs to find their way in.

The company knows this, mentioning in its legal disclaimer: “THOU SHALT NOT USE IT FOR PREGNANCY OR STI PURPOSES.”
