I’ve had lots of partner sex in my life, which when it is working is hard to compare to any other form of sexual pleasure.
That said, I love masturbating and porn, and have had some incredible solo orgasms from the traditional manual method as well as lots of mindblowing orgasms from using a fleshlight.
I have never tried a sex doll but am thinking of getting one since I am deciding to be single for awhile so will be relying on myself for sexual pleasure.
