Yes, but they should be inter related. Anal sex is becoming much more accepted in mainstream society. Many celebrities are sort of publicly admitting to enjoy it, Gwenyth Paltrow for example, Laura Linney also has given hints. (Dream on Right?) Now a days with a younger generation raised on the internet, anal sex is more seen as common. Enema sex is sort of different since it involves pooping. I know most of us are not into scat, but there is still sort of a Taboo that is related to enema sex being so closely related to scat, or may be perceived so by people not familiar with enema fetishes.
I had a lover, 20 years my junior, who gave herself chemical fleet enemas before I would come over because she wanted to clean her bottom out for anal sex and play. I would find out about here fleet enemas and later turn her on to bag enemas with tea or coffee. But when it cam down to it, she just wanted me to fuck her ass, which was fun and all, but I would later fall in love with her and I started fucking her pussy. She was pissed at me when she got pregnant. Should have just kept squirting up her butt.
Enemas and anal sex should be inter connected because, as we all know, a clean and well lubed butt, is best for anal sex and anal play. Anyone who is good at anal sex should also be a good enema giver. The two go hand in hand.
Laura Linney is probably a good 15 years older than me, but I would be completely honored. I would love cleaning out her butt any day..
