Buying her a dildo was bad idea

A while ago a wrote on this subreddit about my girlfriend not letting me improve my stamina, always making me cum before her, and talking more and more about cuckolding during sex.

Some of you took the time to give me some honest advice (which I really appreciated). And one recurring piece of advice was to buy her a dildo. Something more similar to the big dicks she got used to during her slutty phase.

So I did! I ordered a 10" dildo from a website. It was delivered within 48 hours. And at first it seemed like a perfect solution to all our problems. We've been intimate pretty much everyday since I got it. But i'm slowly beginning to regret it...

My girlfriend LOVES the dildo. She orgasms harder with that thing in her pussy than she's ever done with me. She has even started using it by herself, sending me pictures while i'm at work. And I must admit that every time she does I have to take a quick break to masturbate in the bathroom. I feel safe doing so, since it only takes a minute or two, and I don't think anyone would suspect me or believe that it could be done so quickly.

But here's the thing: her using the dildo has made me EVEN MORE of a premature ejaculator.

She always have me wait and watch before letting me have sex with her. "Ladies first", she tells me. And while I don't touch myself (a very strategic choice on my part), the sight alone usually has me leaking precum. It just turns me on so much to see her labia stretched around that thick shaft. Her closing her eyes, biting her lower lip, moaning softly.

After x amount of time and orgasms (usually more than two) she put the dildo away and motions for me to get on top of her. By that time her pussy is dripping wet a feels a lot looser than usual. She usually jokes about not even being able to feel my dick. She is also tired from her orgasms so she just kind of lays there. One time I asked her to change position and she just said "What's the point, honey. It will be over soon anyways". She also likes to point out that there's really no reason for me trying to last anymore.

And she's right. There is no point. My dick has been replaced by the dildo. It's like I have subconsciously given up. Last night I only lasted a couple of thrusts. Even my girlfriend was shocked when I started shaking and breathing heavily, asking me if I was seriously cumming already.

I don't know how to feel about this. On one hand our sex life is better than ever. On the other I feel more and more like a bystander. Because the majority of the time i'm just watching.

I really love her though. And if this makes her happy and satisfied I guess it's all good. At least its just a dildo making her orgasm - not another guy.
