I thoroughly enjoy it. my wife over the years has improved her technique. I am rather girthy so she only sucks on my top 1/2, and I don't try to cram it down her throat, she flicks her tongue on my head, after about 10 minutes my cock is fully engorged, at full length and full girth. at this point, she mounts up and rides her fat boy. she will often BJ me to shorten the rebound time after that initial orgasm.
I'm in my late 50's and when I first started dating, not to many gals would BJ. I had a few gals that would. one was quite fond of it. my wife initially did not, but we watched some porn one nite(remember vcr's and the 80's) and this gal was BJ this guy, and she asked would you like me to do that to you, I said yes. so later when we went to bed, I got my first BJ from her, she could feel my rock hardness, my size increased, she jumped on and had a relatively quick orgasm for her. after that, I got a lot of BJs before ramming her pussy. and I reciprocated, I licked her puss, we 69'd a lot. she always insisted on cumming by my cock, not my tongue, but i persisted a few times and made her cum just by licking. she said she liked cumming and clamping down on my cock.
