Welcome, dear iJerm417!
We here, on EdenFantasys, are happy to help you with your inquiry. The issue of competing with sex toys is one very common problem - we've discussed it plenty in this site, for many years.

We've managed to learn that the reasons for using sex toys are different for everyone, but one thing remains unyielding - if a couple uses sex toys together, sex toys will not drive them apart.

Your girl may like a girthier shaft inside, but it doesn't mean that any silicone or real-skin gadget would ever compete with you. it's not always the matter of size - it's might be the curve, for example, because many toys pack a specially designed curve to hit the G-spot.

She trusts you enough to share her pleasure with you - why not play the part? use the dildos or vibrators on her as foreplay, combine them for a taste of dp, use different combinations of your penis and toys. These experiments will turn your sex life into a roller-coaster of fantastic sensations for both of you and will build up your intimacy and trust.

Another great way to come to terms with sex toys is to get yourself some. For example, you may try a realistic masturbator. It will never mean that you would prefer a silicone experience over the real one - those are simply different things, and you will understand it much more clearly once you try it for yourself.

Hope this helps.
Best of luck, keep us updated on your journey!
