That would mostly depend on the reasons why you haven’t used toys (much) before. If it has to do with your partner feeling “replaced” or “useless” when toys are used, then you’d need to assure them that toys are not AT ALL a replacement for them. After all, toys can’t cuddle, they can’t remember what you like and do it when you’re least expecting it, they can’t provide emotional support during and after, etc.
If you think your partner would be cool with incorporating a toy but you just don’t really know how to bring it up, here are some things you could try:
1. Find a piece of media (e.g. TV show episode, news article, movie, whatever) that references sex toys, show it to your partner casually, and say something like, “How would you feel about trying that?”
2. Send your partner a link to a sex toy shop online and have them pick out a toy that they want. Then buy one for them and one for you.
3. Just talk about it! If you don’t feel comfortable talking to someone about sex, you shouldn’t be having sex with them! Just say, “I’ve been thinking about using sex toys more often during sex. How would you feel about that?”
