So far, I haven't had any STIs, nor did I experience any disadvantages from taking PrEP.
I have only started to let my inner Slut out after starting PrEP and it taking full effect last winter. Primarily, I enjoy anonymous encounters at the local bathhouse or at ABS. Having no knowledge about most of the men I service, PrEP has allowed me to enjoy being an enthusiastic cocksucker with less worry afterwards.
I tend to stay the full six hours during a typical bathouse visit. I average visiting once or twice a month and am getting more comfortable sucking more cocks each visit. As with many venues, it can be hit or miss on numbers of cock and if the men want to cum. During my last two trips, I was able to suck five men, then six men; of those eleven men only three orgasmed in my mouth.
