Sean Lowe and his new wife Catherine Lowe, formerly Catherine Giudici, have opened up about the first time they had sex on their wedding night. 

"[It was] fantastic! I think we both performed extremely well. There was a parade that went through the room, and fireworks!" Sean revealed to Us Weekly in its latest issue.

"[Waiting] has been a great testament for both of us.... We don't regret anything."

The seventeenth-season The Bachelor couple tied the knot on January 26 in a live televised special on ABC entitled The Bachelor: Sean and Catherine's Wedding. Catherine and Sean decided to wait until marriage to have sex and lived in separate places in Dallas, TX -- Sean in his loft apartment and Catherine with one of Sean's best friends -- before the wedding due to Sean's strong faith.

After they said, "I do" and enjoyed their first night as man and wife, the couple reportedly took off for their one-week honeymoon in the French Polynesian islands of Moorea and Bora Bora in the South Pacific. They stayed in an over-water bungalow at the Sofitel Moorea Ia Ora Beach Resort on a private island at the cost of more than $350 a night, according to Us.

"It's like something you'd see in the movies," Sean, 30, explained on the last night of the couple's trip. "We've been treated like royalty."

The pair arrived at their honeymoon destination at 9AM and immediately wanted pina coladas. Sean joked they "looked like a couple of drunkards." That night, the pair enjoyed a romantic five or six-course meal in Bora Bora while watching the sun set behind the mountains.

"We don't leave our room unless we have something we want to look at!" Catherine, 27, told the magazine.

"We were inseparable before, but this is a different level... [We're] having the time of our lives! We are in heaven right now. It's surreal to look at each other and say, 'You are my husband' and 'You are my wife.'"

"It's definitely a bit weird to see a wedding ring on my finger," Sean said. "That makes it much more real. Like, Oh, crap, I'm married! It's an awesome feeling too. About 10 times a day she asks me to call her 'my wife' because she loves hearing it."

Catherine said she also loves being called "Catherine Lowe" now -- one reason being people don't mispronounce it -- and the "most attractive thing" to her is seeing her hubby wear his wedding band.

"We can't wear our rings in the ocean and he said he feels naked without it already. That is so hot to me because it shows his commitment and symbolizes our love for each other," Catherine explained.

The couple took on many "memorable" activities, both thrilling and relaxing, during their honeymoon. Catherine and Sean -- whom his wife dubbed "an adrenaline junkie" -- reportedly went ATV riding through the mud in Moorea to the top of a mountain, paddleboarding, kayaking, snorkeling, and swimming with sharks and stingrays.

"There were stingrays that would come right up to you -- about 20 of them. After I fed one, it tried to eat my crotch, for lack of a better word. I yelled and freaked out. I thought I was going to lose my manhood. But they don't have teeth, just suction," Sean told Us.

"When he started yelling, I was like, 'I'm outta here!'" Catherine joked.

Now that the honeymoon is over, Sean and Catherine are apparently ready to get back to reality and live normal lives.

"We'll be trying to find a new place to live," Catherine said.

"My place is such a bachelor pad. Hopefully we can move out quickly," Sean admitted.

"He has good taste and style. I'm just making sure my stuff can fit," added Catherine, who said she needs a lot of closet space.

The newlyweds are also looking forward to having sex for the first time in their new home once they find it and get settled.

"It will be the greatest thing ever. [The Bachelor host] Chris Harrison is going to introduce the christening of the bed!" Sean joked.

In addition, Sean and Catherine told the magazine they'd like to start having kids "in a year or so." Catherine revealed she'd like to have five children, which Sean admitted "sounds like a lot" since he only has one sibling.
