Sean Lowe has given his bride-to-be Catherine Giudici "a warning" about what might happen the first time they have sex after their wedding.

"From a guy's perspective, I've already kind of given her a warning," the seventeenth-season The Bachelor star told E! News. "If it's not long-lasting the first time, just give me 15 minutes and we'll try it again!"

Giudici cracked up in surprise over Lowe's comment but clearly expressed she doesn't care about that.

"It's not a secret, come on! I mean whatever, I love him!" Giudici, 27, said.

During a separate interview with ABC News, Lowe -- who was previously and widely reported to be a "born-again virgin" -- revealed his excitement to make love to Giudici for the first time, and she insisted she's been happy to wait.

"We made a really good decision for us, and we're excited to consummate as husband and wife," Giudici told ABC News on Wednesday. "It's something that is a benefit of being married."

Lowe, 30, proposed to Giudici during the finale of his The Bachelor edition, which filmed in November 2012 and aired in March the following year.

The couple is set to wed on live television Sunday at 8PM ET/PT on ABC.
