I guess every situation is different... My wife is hot, we've been married for a few years. She takes care of herself, she takes care of me, we do everything together, we're renovating a home together, thoroughly enjoying all the time and effort into picking and doing the floors, kitchen, paint, etc etc. But i fucking love sloppy wet "porn star level" blowjobs. And my wife absolutely doesn't like giving blowjobs. I'm very well groomed and my hygiene is impeccable. As soon as I get home I shower and we usually fuck anyway from 5-7 times per week. I'll put my thumb in her butt while we do doggy, she rims me, i fuck her really hard and sweat... Seriously, we have a great thing.
However... When I've got a raging hard-on and I unzip my pants and grab my cock, the urge to receive oral sex is outrageous. I must be one of those guys that likes blowjobs more than sex. I love it. I had a girlfriend back in the day would give me head to completion because she enjoyed it I've had other girls who enjoying giving head, but not like that one girl; she could impress every single one of us, guaranteed.
So my current wife is amazing. But she'll give me head for 30 seconds and then "complain" about gagging or wanting to fuck... she'll rim me a little, do some BLS, and make love to my Love Pump.... but it'll NEVER be for more than 30 seconds to a minute because she just hates sucking dick and she's always gagging. WHATEVER lol... so that's how it started. I hobby maybe 4-6 times per year and it used to only oral. 30 min blowjobs to completion is all i did at first. However, some of these girls are so fucking hot and good at what they do you can't help but stick your tongue in their ass or fuck them so it's a steady progression.
I'm still happily married and looking forward to fucking my wife but next time she's working on a saturday and i have time to myself i may feel inclined to see who is available for an epic blowjob. That's basically my situation... It's just getting harder and harder to make the time/find the time to hobby
