I like oral sex, I enjoy sucking cock and eating pussy and love it when my partners do the same. In fact, it's one of my criteria with any sex partner! I remember the first time a partner refused to reciprocate, it really pissed me off and helped make me more selective.
I am also a practitioner of safe sex, as we all should be. Condoms, and even a dental dam, prevent more than just an unwanted pregnancy. However, a word of advice for gentlemen who ask for a blow-job ... lubricated condoms kill the mood and taste freaking awful!
