Did I relapse?? Even I’m over day 60..

To give your brain the best chance to heal from pornography addiction, avoiding sexually stimulating images so as not to reinforce the neuropathways in your brain dedicated to PMO is the fastest route available to you. Did you relapse? I think that's up to you to decide. Why are you practicing semen retention? What are you trying to accomplish with this practice?
Yes, you can re-engage the same mental patterns and corresponding parts of the brain without masturbation and ejaculation and thus slow down the healing process NoFap is meant to induce. It may be less detrimental to your goals to avoid masturbation and ejaculation but you're still reinforcing a sexual relationship with a computer screen.

 

Not sure. You mention “fantasy,” which is a mental image, and it takes a lot of mental discipline to stave those off. If being “drawn to images” means you looked some stuff up, then, yeah, you relapsed. Others might not agree, but I’m kind of hard line because that’s the way I’m going to have to be with myself.

Stay safe.
