I initially increased my size with jelqs and stretching. my wife liked my new size, and wanted me bigger. so I got extended blow jobs all the time. lots of edging. overall, gained an inch or so in length and girth. then I got a pump, used it for a few weeks without her knowledge, and noticed that my fat cock got even fatter after 15 minutes of pumping. so at that time, it was pump, shower, get dressed. I walked into our bedroom naked one morning, just as my wife was waking up. her eyes dropped to my crotch, got real big, threw the covers off and spread her legs. after, I told her about the pump. she said, I was so thick, it' was quite a visual turn on. so, sometimes she would ask me "pump it up" this was a few years back. what I found was that over time some of those girth gains become permanent. now, a blow job for me is my wife licking and sucking my cock head. she can't get me in her mouth anymore.
