Not into guys romantically, but from a purely oral sex perspective, giving blowjobs is the single sexual act I am into most. Like to start with them limp and watching and feeling them grow in my mouth is intoxicating. Pulsating veins, deep-throating them, feeling your oxygen being cut-off, feeling that dick twitch, inhaling male musk, sucking on balls - all leading up to the blast of cum either shot directly into my mouth and swallowing or jacking it all over my face - cocks just offer such a dynamic range of goodness. Cocks can really take over my brain unlike pussy ever has.
