And it appears the bizarre proposal went down well as his new fiancee took to social media to boast about the engagement.
The unnamed woman even offered her gal pals advice on how to bag the perfect man - give great oral s-x, cook for him and don't be a c***.
The newly-engaged lady seemed content to shun a traditional proposal, writing on Facebook: "Last night, he asked me to blow him.
“I put my hands on his c**k and this is what I pulled out.
“He is truly a blessing in my life. I wouldn’t ask for anything else.
“In a perfect relationship, don’t date a broke f*** and if you give him the best head he’ll ever get, cook him food and don’t be a c***, you might get a 1.6c diamond too.”
It appears the post was originally posted back in 2015, but has recently been shared again.
It is not clear whether the happy woman made it down the aisle with her romantic fiancé, or whether they are still together.
