Research has shown that respondents who reported more variety and new experiences (such as new positions, romantic outings, discussing fantasies) had higher relationship satisfaction. Variety in sexual activities and sexual novelty positively correlate with higher sexual satisfaction. (1)

Why is variety important in a relationship?
It becomes important to experiment with your sex life if you notice your relationship is lagging for any reason. But what do you do if you love your partner and can’t cheat on or share them with someone else, like swingers do? This is when you can introduce a sex doll to spice up your relationship a bit. It can be an outlet for problems in your relationship without cheating on your partner.

How does a sex doll provide variety?
A sex doll is a safe alternative when you have no experience with threesomes, partner swapping, or swingers clubs. This way, you can sample this kind of variety through a lifelike sex doll.
A full-size sex doll offers a realistic alternative so you can safely experiment with your own fantasies and desires without losing control.
A sex doll acts as an extra partner or person within the sexual relationship. A sex doll doesn’t have to be used only for sex but can also provide companionship at home without immediate use.

What are the benefits?
The benefits of sex dolls are:
- With a sex doll, you can’t cheat, so you remain faithful to your partner
- You always maintain control and can start and stop using a sex doll whenever you want
- It’s less awkward than with a new person, since you don’t have to be social with a sex doll
- A sex doll does exactly what you want; you don’t have to ask for permission
- Sex dolls are always available and you can call on them whenever you want
- You can choose the appearance of a sex doll yourself, so you pick a partner that fully meets your physical preferences
- A sex doll requires no effort; you don’t have to find someone, persuade them to share the bed, or ask if they’re interested
In short, with a sex doll you stay faithful to your current partner, choose the ideal appearance, have full control whenever you want, and avoid social challenges.
Adding a sex doll to your relationship is easy, simple, and straightforward.
Additionally, (not always) when introducing a sex doll, a slight tension or form of jealousy may arise from the woman. When a man is involved with a sex doll, this can evoke feelings of loss of ownership in the woman, making her feel more attracted to him.

What are the disadvantages of a sex doll in a relationship?
Since a sex doll cannot think or move on its own, it requires input; you are the leader in the relationship dynamic. You are the one who must use, direct, and clean the sex doll. You bring animation or life to the sex doll, which requires some imagination.
Additionally, sex dolls are quite an investment, think of 700-1300 euros for a quality TPE doll. Silicone sex dolls cost 2-3 times more than TPE dolls but are also more durable.
If you have enough energy, imagination, and budget, the disadvantages of a silicone sex doll are negligible.
Our experience
We have received emails from customers who actually benefited from adding sex dolls or torso dolls to their bedroom routines. The routine was gone, and every weekend became a new celebration from which both could derive pleasure. It is truly possible, and as a webshop owner, this makes us very satisfied that we can save relationships by giving them new life.
