I was a chaser myself, so for me PrEP was not something I considered at all. That said, I don't have any issues with guys being on PrEP. Every individual is different and nobody should have to justify their choices when it comes to one's sex life and health. It's all about living out one's fantasies and making informed decisions. So if someone likes to bareback but wants to avoid contracting HIV, sure go on PrEP; if you like to fuck bare and are unsure about how you'd feel if you turned poz, sure go on PrEP (for the time being).
Even though PrEP was not for me (for obvious reasons), I also feel that it has its benefits for the barebacking community as a whole. Thanks to PrEP a lot more people are finally giving in to their urges and fuck raw... and who am I to turn down a stud's load?!
