SSBBW Lover:
I'd be surprised if most of the people on FF aren't constantly or frequently sexually aroused by their gaining. And those who are FAs are most likely here for visual arousal. Although I'm gaining in secret, because my partner is not an FA, I'm finding that the fatter I get, the more I desire a fatsexual SSBBW partner, and the more I masturbate to thoughts of my own weight gain and that of an SSBBW partner I wish I had. For me at least, fat is hyperarousing. On me and on the huge, horny, gluttonous woman I wish I had as a partner.
I am in the exact same type of relationship with my wife. I get so turned on by my own fattening and the thought of having a SSBBW wife would be the ultimate.
