Also wondering if it helps a positive but sex-starved marriage?
Hi and welcome to the forums,
I assume you are talking about TUTH? It really depends though, and I have to note that it can be more than adding pheromones. Although TUTH helps to get women in the mood, it can also be a strong repellant and turn down women (they get angry and start yelling at you). Think of TUTH as something that will make you more “manly” in bed, so if the sex isn’t that great, TUTH will help. If you sleep in different rooms, then I think its best to think about relationship counselling or trying to get her relaxed.
Having that said, I don’t know too much about your relationship and the reason why you came here, so please… Do tell us a bit more about yourself and hopefully Dee will help you too.
Our relationship is good, but the sex is lackluster. That’s pretty much it in nutshell.
From what I know and experienced, TUTH is a sexual booster. It makes me more aggressive, gives out a more “dominant” vibe, and it creates a sexual tension in the air. I would suggest if you want to use TUTH, you should also create the mood for it, else she will get dominant and cocky and you end up sleeping on the couch (that can happen). Bring the kids to family, make her feel comfortable, and have a good dinner together. Just before or after dinner make yourself look good, spray a bit of TUTH on you (not too much, 1 or 2 sprays work fine, and knowing that you are in your 40’s, i think x2 is better), make a romantic mood with “just you and me,”, let her know why she is the woman of your dreams, and things will start off from there. Pheromones are like booster rockets, but you need to steer them in the right direction.
If you are not the romantic type, I think that doing a bit more in the house, helping her with the kids, and using just 1-2 sprays of TUTH like an hour or 2 before you go to bed does also help a lot. She needs to be in a relaxed & cuddly mood, if she is more relaxed and you have some TUTH on you, it will surely end up with some oldfashioned romance 
Mr Seeker has it right… Foreplay starts for us waaaaay outside the bedroom.
Most of the time something simple or effort to show you are genuinely attempting to help can be better than the most expensive roses…and will go a long way for you later. IH can help bridge the divide in rapport also if you aren’t talking much.
Hi Starrman,
Yes TUTH will definitely put her in the mood when used right. TUTH is part of a complete package and you must act on it to or it is useless.
IS now I suggest this to because it does help put her in a good moodand feel good also. The IS you can wear around her anytime. This will boost your confidence and you will come off as a young fertile vibrant man.
Welcome to PheromoneTalk Starrman!
TUTH might help you indeed if that nut shell is accurate.
Happy Pheroing! 
Thank you for the information everyone. Much appreciated.
