No doubt - we've had 23 great years together and thing are hotter now than ever. Honestly there were times when it wasn't so great - you have to work through that. Communication and the desire to give your partner pleasure will help. When the kids get older and have their own lives, you get to rediscover your partner.
Choose well - and you should be set for life.
Honestly it's kinda sad to go to single's bars and watch 30 & 40 somethings desperate to 'hook-up'.
