Dealing with porn addiction&ED

I'll explain my situation I started porn& masturbation when I was 14 and I was doing it daily till 16 than I had my girlfriend and started doing sex everything was until 18 then we broke up and I stayed single didn't have someone in my life for for a long time but I had long time affairs at 20 I had hpv which I did get it lasered and didn't had sex for a year I just focused on myself and my treatment eating healthy and exercising regularly and the meds to get rid of the hpv.I didn't had sex till 20-to 21-22 I just masturbated because I didn't know how to approach someone and didn't wanna give them too.I moved to tropical island in Thailand for almost a year at the start everything was perfect I was getting hard all the time having one night stands and short term affairs and a lot masturbation,after that I met with a girl named Jade and had a long term affair but we kept talking for a long time,after she left I met with someone else after but didn't get hard for some reason and was so devastated by the experience. This is where I started having problems, after that I met with someone else after 2 months I had problems with ED and didn't wanted to not be able to get hard so I took Viagra everything was perfect for the night and the day following it.Than I moved back to my country a bit strict and religious.And jade was saying she was going to visit so didn't feel like having someone else at the time I waited for her.By the time I was masturbating but morning woods were weaker compared to past and I was forcing myself to masturbate I was masturbating because ı wanted to not because my body made a reaction,I tested for testeone and any sexual diseases.Nothing was wrong,When jade came everything was perfect for a month no problems at all,Random erections good sex than we decided to part our ways.A month later I met with someone randomly at the party she asked me to stay with after the party and I wentto her place when we get to her bed I was scared from the past and was scared there was a constant thinking in my brain I said I didn't wanna have sex that time because I wasn't feeling like that but it was so odd for me there's a half naked girl teasing next to you and still couldn't get hard.After that I went to pharmacy for Viagra I took the pills and went back to hers Viagra just gave me headache didn't do much I was getting hard it was like %65 I stayed at her for a week and didn't we but had sex for couple times in that following week and I didn't cum but we had sex which was going for 30 minutes but I never got all the way hard like really really,last day before I was leaving we had one last sex and I came but still didn't hard.And that was my last sexual experience with someone else in the past 4 months I tried to not to force myself to masturbate and didn't masturbate for a month I went to urology again for testerone check but everything was good.and masturbation's are so quick compared to past it took s 3-4minutes normally I would search and tease for half an hour.Im planning to start therapy but I don't know where start and to do :(
