I’m a man so maybe it’s different but having tried both, that certainly isn’t the case for me. Without sexual release I just want to cum. It doesn’t inspire me to do anything else that won’t move me towards that goal. Maybe if masturbation were impossible it would be a different story but as it stands the only purpose being frustrated serves is to distract me from non-sexual tasks. Being lonely on the other hand does inspire me to go out and do things and maintain relationships but it’s not for sex. If I’m frustrated in that regard I’d rather just stay home and jerk off. That’s a sure thing rather than the incredibly low chance I’ll meet someone that wants to fuck me right away.
