In any relationship, it should not be a big deal bring up any topic between the two of you. This is especially important when it comes to discussing sexual matters. The reality is far from perfect. Those who do not mind using sex toys, and those who are interested in doing so, thus find it difficult to talk about it when their partners are not so open-minded.
There is a feeling of inadequacy people get when they are told a new entity is about to join their intimate space. These new toys come in to try and take their place; at least that is how they feel. So when a partner says they would like to try them out, it is immediately understood that their efforts have not been amounting to much. To ensure there is a clear understanding and hopefully an acceptance, this topic needs to be raised gently.
There is always the danger that your partner might start viewing you as not normal if you suggest to try out such toys. The usual sexual subjects are already hard as they are. You need to choose your words carefully when bringing up such a topic. The benefits for the both of you need to outweigh their doubts. They in turn need to feel respected and appreciated, and not in any way inadequate. At all times, remain honest and open.
It is important your timing of when to have such a discussion. The place and time matters a lot to its outcome. It is not a good idea to talk about such when you are in the throes of passion. Neither should you do it when you have just fought. In case the both of you have had a rough day, this is the last thing you want to talk about.
This is something that needs to be taken with all the seriousness it deserves. You need to do it at a neutral location. It needs to also be private. There shall be the beginning where either surprise or shock might be exhibited; stick with it. After that, you need to stay objective and set some ground rules and boundaries. You need at first to keep it simple. The more you get into them, the more you shall be ready for more complicated things.
You need to both choose these toys. You do not need to go to a physical store. There is now online shopping. You should not rush into it, as you both need to be comfortable. There needs to be plenty of lubrication so that the toys do not injure either of you. These toys are not a reflection of an insane couple. They are the things that have saved quite a number of sex lives in most committed relationships out there.
