I think it can be .. when I met my partner, she was slim and I don't think she considered fat especially kinky, but then when I introduced her to feedism she absolutely loved it and she put on a stack of weight, which is awesome.
Then she started encouraging me to gain weight, and i've embraced it too so yeah maybe its contagious haha

It’s contagious by the mere fact one’s friends or spouse is accepting of them in the first place :-) Getting fat together is fulfilling all the more ;-)

I’ll join the Can Be contingent, though one overlooked major factor is how easy/difficult it is for the person in question to fatten.

Example: me. I had an intestinal surgery a couple of decades ago to save my life. Wasn’t technically WLS, but has had much of the same effect, which since i started out “average” for me is Very Not Good for health and survival. All this time i’ve routinely consumed things that outright blow most people up with plushness (e.g. heavy cream), and no matter how extreme, my lifetime peak has been 180 lbs. on a medium build 1.8 m tall frame (how’s that for mixing units of measure?).

OK i’m atypical, but quite a few people don’t readily get fat, per self-reports in this community over the years. I guess we have immunity.

Welcome back, Jack! (JCIV)

During high school I always dated the fat boys because I thought they were more intelligent and had nicer personalities.
I was pretty skinny and never gained any weight while dating them or being around their families.

I will say when I started coming on size acceptance sites on the internet I made a lot of friends and with their help I managed to start gaining.

I was fat most of my childhood and lost 30 lbs. between junior and senior year in high school. I found myself dating senior year and the 3 girls I dated were all on the chubby side. I had always been attracted to plumper girls and remember enjoying watching the girls in my class gain weight due to puberty and maturing. And I had a school boy crush on a couple of chubby teachers in grammer school.

Fast forward to adult hood and when I reached my middle 30's I found myself slowly gaining weight back to my heaviest, which at the time was 205 lbs. Thanks to sites like these I found myself getting turned on by bigger and bigger women and the desire to gain weight myself, became ever stronger. Over a ten year period I put on 130 lbs., starting at 175 and topping out at 305. The fatter I got, the more sexually aroused I became so I would say for me getting fat was contagious and being a fat guy for the rest of my life has been very pleasurable even though there are some health and mobility issues that have come along with it.

for me, i was 160 lbs when i moved in with my ssbbw girlfriend. i don''t think her fat was contagious, but maybe our lifestyle was. we spent a lot of time going out, drinking, eating out a lot. i started to partake in the treats and things that she enjoyed, and all the drinking cut down my trips to the gym due to hangovers, lol. so eventually i just decided to give in to the lifestyle for a little while... but the slippery slope has resulted in me continuing to gain and i haven't been to a gym in years!

Finally, a virus I actually want to catch!

Being around heavier people has caused me to think in similar terms. As a result, I'm twenty five pounds heavier than I was a couple of years ago. I don't have any plans of losing it at this time.
