I fucked around and found out, advice needed..

My wife has never been able to cum from PIV only sex with me. I have a rather straight and not exactly super girthy member.

She had expressed that she wanted to try a a big dildo recently so I got a couple. One of them being a really curved one.

Anyway, this curved dildo is longer and thicker than my penis and has a really aggressive upwards curve. I used this on her and she came for the first time ever from purely PIV in literally about 1 minute only..

This actually has destroyed my confidence now as I've had sex with her for Hours before at a time and still can't get her off this way. I feel inadequate now and like we're not sexually compatible. She expressed she doesn't feel this way and she enjoys sex with me and that I can even throw the dildo out if I want but I saw how it made her feel and I literally cannot make her cum that way with my dick.. and I just can't get over it now imagining someone else with a similar shaped dick as that dildo can get her off like that.

What should I do about this?

Update: WOW I did not except such a huge response to this post. Reading through a lot of these comments really helps guys. I'm feeling a lot better about this to be honest and talked with her more about it today.

As far as I'm concerned if I can get over the insecurity of mine, this was a really good idea and introducing sex toys is definitely spicing things up for us.

To the fellow men out there even the ones above average, if you can get over the insecurity of introducing sex toys like dildos bigger and/or with different curves than your own member, I think your woman will thank you because mine certainly is after what she told me today.

And for what it's worth, she wants my D as much as ever if not more after trying this.
