I don't dislike anal sex, it doesn't disgust me, I'm just not that into it, and I'd rather make out and j/o, do oral sex instead, nipple play, CBT, maybe rimming (this is assuming everything's clean inside and out and I know him well), or do some bondage/SM.
If I were to fuck someone I'd want him to be a boyfriend/partner/husband and I think I'd only want to do it every so often, maybe once a year or a few times a year, not all the time. I'd do it to please him and because he wanted it. I've had sexy dreams about fucking men and sometimes I'll think about it when I jack off but I'd only want to do that with a boyfriend/partner.
A friend of mine says how I'm a top since I don't want to be fucked at all if I was doing anal sex, but I don't really go by that label/role, and even for BDSM I say I'm a switch that leans towards the dominant side. He's a natural bottom since he easily progressed from one finger to multiple fingers to a 7" dildo very fast. I've tried fingers and small toys and all I get is discomfort and it just feels like I'm taking a crap backwards. The most I can take is a finger and that's only when I really want to.
