I have had the same dilemma. With my ex I just brought it up, and then she said that "start make me gain" which I did. She started at 80 kg and gained to 113 kg. But she was not into it, more did it for me or what ever reason. After some years it was not fun for eighter of us as she was no true fa, gainer or feedee. Though we got children and were mostly happy, but ended up separated after yet some years.
I also know after living with a even larger good looking bbw, who doesn't share the kink, despite being fat and good looking, that eighther you got something from these kinks, or you don't. The result is that if she doesn't share any of it, you both will end up frustrated. The only way around it is to find a woman that shares it. Nothing else will work in the long run. If you can't supress your kink, which often is hard.
But I wish you all good luck! Maybe she is a feedee without knowing it!
If you don't mind, tell us the outcome 😀

I've had the same dilemma as you a couple years back when I started dating my now fiancee. It just came naturally, I haven't had to force this conversation. One day we were talking and I've just told her. While she's not a feedee, and will never be most probably she accepts my kink and we're living peacefully.

Ditzy:
Dating for me was better after gaining quite a bit of weight.
When I was really skinny guys never gave me a second look.

I think we all have doubts about things we do.
I did when I started attempting to gain weight.
Pretty normal really.

Ah the ever present struggle of wanting to fit in to our diet obsessed society vs. Wanting to just break free... it depends on your priorities - if being fat is more important/enjoyable to you than being physically fit, then work on your fitness, if being fit is more important than enjoying this kink and a bigger body, do that. You can also make an effort to be fit while gaining, just keep up exercising but ensure your intake is more calories than you're losing. It will be a slower gain, but you'll probably find it more sustainable long-term.

As for dating, perhaps you may have an easier time finding a partner while thin, but it's also more likely they'll be toxic towards your weight gain when/if you do gain. Personally if you want to gain, I'd just gain and date at the same time, and when you do find someone you want yo go ling term with, all the more likely bring fat will be just fine. Fat people date all the time (exhibit A, see dating ads on this website).

I really want to be obese, I know I’ve always dreamed of it. But I also really like doing sports like cycling or tennis.
How do you manage to do both?
I already gained 25lbs. But I can already feel that doing sport is more difficult. Problem is that I want my body way softer, it’s only the beginning of my journey!
Do you have any tips or advices about that?

Wish you all a good day!

I was on a wrestling team when I was 315lbs so while some/most sports may become more challenging at a higher weight it's still possible you just have to want it. Also, to gain weight you only need to be in a calorie surplus, the body doesn't care where the calories come from they're just calories it stores them the same regardless. As Munchies said above you can gain weight perfectly fine by just eating a large amount of healthy food.

Zlukz:
Thanks for your answer 😊 Let’s say that ice cream is working very well to get fatter 😅 But I’m alongside eating diversified food.

Maybe I should get away from cycling and think about making judo again. So then my weight won’t count 😁

Fat Dreams:
What about sports that involve water, like rowing and/or swimming? It's a great way to get cardio in and weight doesn't affect your performance as much.

Enas:
What about cycling? 🤔
(asking because i really love cycling!)

Zlukz:
That sport is also one of those that I used to practice and I still love this sport. But I’m starting to be a little plump in my cycling clothes and I have difficulties to do the same distances than the ones I used to ride. Any tips for fat cycling ?

Enas:
OH i dont have any clothes specific for cycling, i just care about the distances i can cover! (I would love to go into a trip in the mountains with my bicycle and potentially other people with theirs too! I just dont wanna polute while having a fun trip! >~

Zlukz:
Would love too but I’m starting to be too fat to do such a thing 😅

Enas:
Well, if you train hard enough, youll be able to do it!

As for me, it will be much more difficult! XD

Munchies:
This is pretty much the long and the short of it.

I will concede that you will have to adapt at a certain point. However, if you can maintain your fitness, you will be able to cycle just fine.

The only trick is that you will need to keep your caloric intake up. You'll build some muscle, but you can still be squishy. Just remember to keep junk food as a sometimes food. Your body will need a lot of nutrition that you can't get with a junk food-based diet.
