So, I've been taking this drug [ropinirole] that stimulates the release of dopamine. Other people have had major trouble with it, but I've been okay with it because suddenly loving masturbating again after a long time has been really cool. I get naked every day, get out the lube, cue up some female friendly, lesbian or bi porn (Shout out to Malena Morgan! You're a fucking girl on girl sexpert and I've cummed to you so many times.) and then I smear myself from ass to tits with lube or petrolatum and rub and prod for at least 8 hours per 24 hour period. This has been going on for at least three weeks. I woke up this morning at 4 and started rubbing and fingering myself. I did have sex last weekend. I was at a party, and some 23 year old kid, a friend of one of my good friend's son, was kind of drunk and REALLY horny. He started hitting on me hard, which I thought was weird and suspicious, but he let me feel his dick, and it was rock hard. He was cute and young with a decent sized dick, so I wasn't going to pass this up. I took him back to my place, and we went at it for 2 to 3 hours. I sucked his dick, and he stuck it in my pussy and my ass. I let him do whatever he wanted as long as it wasn't violent or painful. When he had to come, I told him to come in me, and I held his ass and pulled him deeper as he blew his load. Then he wanted to kiss for about 10 minutes, which was nice. The next morning, he was hard again, and I let him fuck me, of course. It was really good, and I told him he can come back anytime. Now I'm going to lube up and try to get to that point where the orgasms hit like a skipping stone hitting water.

For context, ropinirole is almost identical to the non-ergoline DA pramipexole, which itself works similarly to the classic Peaty DAs like lisuride and metergoline.
