Both. I often have to keep a close eye on my thought patterns when in public, and I have a few strategies to quickly distract my mind before these thoughts escalate ("Think unsexy thoughts!", as my favourite TV show aptly puts it). There are also ways to get me going through touch - I have a particular weakness for having a finger softly traced along my spine.
It can be a blessing in that sex is ridiculously easy to come by. Personal advert listings are basically a smorgasbord for people like me; find someone you like the look of, dial the number/send an email, meet in a few hours for easy satisfaction.
The catch is threefold. One, love can be tricky: sticking with a partner who can't match my tremendous sexual appetite can potentially undercut the relationship as a whole, and that's not fair on either of us. Two, sex is actually pretty expensive - I've spaffed an obscene sum of cash on contraceptives and lubricant throughout the years, to say nothing of all the sex toys I've accumulated throughout. Third, there's the matter of health. During my worst phase (early 20s), the staff at the local STI clinic all knew me by name. A particularly nasty pregnancy scare is actually what finally convinced me to go and see a therapist about it a few years ago, and I've kept my urges under much better control since.
