Why Jessa Duggar Wants to Plan Out Her First Kiss With Ben Seewald

— -- Like her sister Jill, Jessa Duggar is waiting for her wedding to have her first kiss with her fiancé.

To say they're excited would be an understatement.

"We’re really looking forward to the first kiss!" she told ABC News. "We're talking about it -- what if we miss or mess up? We're gonna have to plan this out or something!"

Duggar, 21, announced her engagement to Ben Seewald, 19, earlier this month. It will be documented on "19 Kids & Counting," her family's reality TV show, which premieres on Sept. 2 at 9/8 p.m. CT on TLC. Fans will also get to see Duggar plan her wedding, which she promises will differ from her Jill's nuptials this past June.

"The guest list is pretty big, but not as big as my sisters" she said. "My list is a little smaller [than Jill's was], but then Ben’s guest list is bigger Derick's. It will be another Duggar-sized wedding!"

The reality TV star said that she and her future husband hope to tie the knot this fall or winter. They've already begun thinking about their color scheme (no, nothing has been chosen yet) and who they'd like to tap to be their bridesmaids and groomsmen (yes, their families will be involved).

However, both Duggar and Seewald are focused on making sure that their wedding is cost efficient and are considering re-using Jill's decorations and flower girl dresses.

"We’re gonna go really simple with a lot of our food and even flowers and that type of stuff. People spend so much on flowers, it’s outrageous!" Duggar said. "I'll go to the grocery and buy flowers! I don’t know how many flowers we'll have in nature if it's cold outside but I was like, 'How about we just go pick [some]?'"

"We want to have a nice wedding that everyone will enjoy but at the same time, we’d like to push our budget more toward our honeymoon because that’s our time together," added Seewald, who said that TLC will also document some of their getaway. "That’s our first few weeks together."
