Fingered my ass for the first time

so recently I've been getting into gay porn and fantasising about being pounded by guys so I wanted to try out how it felt for once and I was shocked at how different the pleasure from my prostate is but I had to stimulate my nipples simultaneously to feel anything close to how a regular jerk off session would feel I've done it twice now and I want to cum from having my prostate stimulated the latest I've fingered myself was better than the first what can I do?
