Internet - There's a new way to wrap up your sexy time while staying in the sheets - "Swaddling" sex has been taking the love world by storm, but what does it actually involve?

Singles who want to intermingle, those who have spring fever, or partners who want to spice up their pandemic routine can celebrate. A new sex position has come along just in time to end the night tangled up in the blankets.

The swaddling sex trend is a fresh option for lovers who want to sleep while still entwined in the throes of passion. As Cosmopolitan puts it: "When two partners agree to fall asleep in the midst of penetration."

As a penis or sex toy remains inside, consenting couples testing out the theory have taken rest-and-relaxation to a whole new level. Sex swaddlers can either lye on top of one another, or in a spooning position for a more intense form of all-night cuddling.

Sex experts warn that adventurous partners should be aware of certain things before they try swaddling. For starters, couples should avoid using common male condoms when attempting the position, to avoid any risk.

"A condom may slip off if your partner coughs, sneezes, moves suddenly, ejaculates (it happens!), or goes flaccid after a certain amount of time," said New York sex therapist Sandi Kaufman.

She also said that the slippery rubber can get caught inside a woman's vagina and pose a high risk of infection. For protection against STDs and pregnancy, internal female condoms were recommended instead.
