A trip to one of these titillating stores provides plenty of ideas to stimulate your sex life, great gifts for your friends or significant other and even a helping hand for that special alone time. Toys you never knew existed are sure to provide an educational experience as well. From nasty treats to X-rated surprises, these places have it all.

One of the most unique places to find hilarious gag gifts with a tasty twist is Sweet ‘N’ Nasty, located right off Newbury Street at 90A Mass. Ave.

According to sales associate Alison Brown, it’s the only sex bakery in Boston.

Sweet ‘N’ Nasty specializes in cakes, cupcakes and candies featuring sexy decorations and catch phrases. The four most popular cakes, all baked on site, are “make a wish and blow,” “the best is yet to cum,” “eat me” and “breast wishes.” The golden or chocolate cakes come in half a dozen sizes; the smallest cakes cost $22.95.

Cakes come made to order with hundreds of designs featuring penises, breasts, handcuffs, naked figures and much more. If you’re stuck on what to choose, there’s a giant book on the counter featuring every design and phrase offered. Orders can also be placed on the store’s Web site at sweet-n-nasty.com, with free shipping on orders more than $100.

Some less pricey goodies at Sweet ‘N’ Nasty include the $1.39 penis pops, $2.99 breast pops and X-rated cupcakes for $1.90, all in white or dark chocolate. With the holidays coming around the corner, cards are also available. “On the fifth day of Christmas, my true love gave to me . five golden clit rings.” Greetings like these are sure to make the holidays special this year.

Sweet ‘N’ Nasty has other novelties such as adult dice games, blow-up dolls, chocolate body paint and edible lubricants. There’s a small selection of vibrators and lingerie. The items featured here are great gifts for birthdays, Valentine’s Day, bachlorette parties or just a delightfully dirty treat to brighten someone’s mood.

“We do all sorts of occasions. In fact, someone is coming in tonight to pick up a cake for his boss,” Brown said.

Here’s hoping this guy’s boss has a dirty sense of humor.

Erotic cakes too much to swallow? Condomworld is located at 322 Newbury Street, just below Newbury Comics.

As suggested by its name, Condomworld has an impressive array of prophylactics-just about every type in existence. There are the basic Trojans and Lifestyles, plus specialties like edible sheaths and Kimono Microthins ($15.95/pack), designed to feel like there’s barely a condom there at all. Two full shelves of lubricants feature half a dozen brands, including edible gels in almost every flavor.

The store’s manager of 12 years, who prefers to be known only as Mike, said Condomworld is different than other sex shops because of its bright and cheery atmosphere.

“The store is fun and exciting, and everybody’s happy,” he said.

The store has loads of fun gag gifts, like breast-shaped pasta, body paints, cards and books, including one every guy should own: “The Lowdown on Going Down.”

The selection of games can spice up any boring date; there’s sexual trivia, truth or dare, water guns in the shape of breasts and even pecker toss, a dirty twist on the classic horseshoe game. Another great gift idea is Kama Sutra’s line of body oils and massaging lotions.

Deeper inside the store, the wall is lined with toys such as anal beads, strap-ons, dildos and vibrators. The very back of Condomworld has tobacco products including glass pipes. There’s even a case of body jewelry with a wide selection of belly rings.

Amazing, the largest adult retail chain in the nation, is located on the corner of Stuart Street right next to Montien Thai restaurant. With more than 40 stores in 10 states, there are a perfect 10 in Massachusetts alone.

This two-level store has a huge selection of pornographic DVDs to buy or rent-the bottom level is completely dedicated to movies and magazines organized by category. With an outstanding selection, if Amazing doesn’t have it, it’s safe to say it probably doesn’t exist.

According to manager Bill Palmer, “We cater to a lot of couples. We stand by whatever we sell and try to help customers as much as possible.”

Palmer also said the store’s most popular product is the vibrating jack rabbit, a vibrator that comes in various sizes costing from $50 to $100.

The main level has a lot of fun goodies such as nurse and school girl outfits, oral delight gels, hand cuffs and vibrators. Every Tuesday is a special event for the ladies-20% off all products all day.

Late-night shoppers are in luck: Amazing is open until midnight on weekdays and 1 a.m. on weekends.

Further away from campus, a more hands-on experience is available at Good Vibrations, at 308A Harvard St. in Brookline. On the T, take the C-train on the Green Line to Coolidge Corner.

Originally based in San Francisco, the Brookline store is Good Vibrations’ first East Coast location.

The idea was conceived by sex therapist and educator Joani Blank in 1977. According to the Web site, goodvibes.com, Blank was dismayed by the lack of resources for women seeking accurate sex information and quality toys, so she decided to open her own store.

Sorry guys, but this store’s products are geared toward pleasing the ladies.

Good Vibrations offers dozen of workshops each year for both men and women. Some are free and most are under $30. On Dec. 3, a free workshop called “Best Lesbian Erotica 2007 Reading” will be held at the store from 3 to 5 p.m..

On the same day, a $25 workshop called “Transform Your Relationship: Sexual Skills for FTMs, Transmen and their Romantic Partners,” will be held from 8 to 10 p.m.

Confused?

FTM is short for for female-to-male, while transmen refers to anyone in transition between two sexes, or someone who does not wish to label him/herself as one gender or the other.

A complete list of upcoming workshops is available on the store’s Web site.

If you’re too shy to come inside these stores, check out their Web sites instead. After all, everyone needs a little sexual healing now and then.
