Condoms should not be worn all the time. Not all people can conceive, and many people know 100% that neither they nor their partners have any STDs in which case condoms aren't needed. Also, if a woman has been on the pill for more than a year the chances of getting pregnant are beyond reason for more protection. What do you mean by love yourself? Whackoff? Also, what if someone wants to get pregnatn? Obviously a condom shouldn't be used. What if the guy is allergic to latex? What about a man who is able to perform a "pull-out" with consistancy? Yes, some sperm can be released before orgasm, but the last I heard, that sperm isn't able to impregnate a woman. Finally, what if a man is able to orgasm without ejaculation? I don't know about others, but I can, and I don't consider myself to be physically unique.
EDIT: Who doesn't think about anal sex every ten or so seconds?
