I think it depends on the person and the circumstances but I certainly think it can. There are several factors at play. One is how sexually attracted you are to your SO and how much sexual chemistry there is with that person. There are guys out there that marry women they aren't that attracted to but are good women, who they love and respect and have common interests with. If you are out mongering with 7/8s regularly and you aren't that attracted to your SO then getting aroused is going to be more of a challenge. Some of it is probably age and health related as well. If you are 28 years old in great health with high T, then it probably isn't going to be that much of an issue. If you are a 55 smoker who is overweight it's going to be more challenging. I think it's different than porn addiction but there are similarities because its impacts arousal. But again, a lot of this is specific to the individual.
