Can masturbating or toys become a crutch to sex w/ someone else?

So you could say I had an early start when it came to "finding myself" ( 6th grade I was in the bathtub and I found out the detachable showered could do more than clean). So basically I've always been in the game when it came to masturbating I loved it ! I feel like at one point I became a little obsessive over it in my teenage years.

Then at the end of my senior year I became very much sexually active to my still partner. It took a experimental two months for him to actually get me to cum but I wasn't complaining since we were both new to the idea of penetration & sex in general.

So the weeks went on and one day we decided to use a vibrator (since I could always cum with that by myself) on me while intercourse and it was THE BEST THING SINCE ICECREAM. We started using it more and more to the point it was like I couldn't cum without it. It made me feel bad cause I think it messed with his ego a bit that he "couldn't do it by himself" I also felt that way if I masturbated a lot I wasn't able to cum as easy with him.

So after awhile I basically quit the vibrator thing for the most part because it felt so great cumming with him. And I also don't masturbate as much but it's just because I don't have the time lol (but I'll treat myself every once in a while lol!
