I'm of "a certain age" and came out just as the health crisis was hitting panic mode in the early '80s. As a consequence, I've had relatively few partners and less sex than one might think of a healthy gay male. Sex has been fun when it happened, but there was considerable worry and angst associated with it as well. (Frankly, I harbor a lot of jealousy over the life I should have had: I paid the price for being gay, but didn't get the supposed benefits.)
Within the past year, I started PrEP. I can't say that I've become particularly slutty, but I can say that the worries I used to have have been greatly reduced. I love to bottom and it's made all the difference in the world for me. I still check my partners' statuses and play safe if bottoming for a positive guy; but I'm more inclined to bareback for a guy who is also on PrEP.
Does that make me a slut? I don't think so, though your mileage may vary.
