I’m under average sized, but my fiancé and I have a good sex life. She enjoys sex with me (that part isn’t in question). She reacts and sometimes even has light PIV orgasms when we do.

She’s also shared that in some positions she doesn’t feel as much physically. She still values the emotional connection and wants me inside her, and we do this very often.

However, after some conversation, we agreed to buy an expensive very realistic dildo that’s significantly larger than me… The size difference is obvious, and when we use it together, her physical reactions and orgasms are noticeably more intense. I use it with a harness and pretend it’s me, and I know for certain that’s the only reason it even works for her. For context I’m 4” long and 4” circumference, and the dildo is 8” long by 6”.

I know a lot of guys might find this embarrassing, but I like to see her get pleasure. Do you see any potential downside to this?
