Here are some words [definitive] on penis size and condoms. Trojan makes a condom from lamb/sheep gut, but not good for STD protection. I have a lady who says she's allergic to latex and prefers the lamb skins. OMG!

Type of Trojan Condoms
There are about twenty-nine varieties of Trojan brand condoms that can be classified according to four different criteria: the material they are made of, their ‘fit’, their ‘design’, and the lubrication factor.
MATERIAL
All Trojan brand condoms are made of latex with the exception of the TROJAN Supra® condom, which is made of ultra-thin medical grade polyurethane, and the TROJAN Naturalamb Skin condom made of a natural membrane. Both of these are suitable for people with latex allergies, but the TROJAN Naturalamb Skin condom does not provide protection against STDs because of the size of the pores in the natural skin they are made of. Both these varieties enhance sexual pleasure since they are designed to transmit body heat. The TROJAN Naturalamb Skin condom is wider and longer than most condoms, and is lubricated. Since it is not made of latex, the TROJAN Supra® can be used with both oil-based and water-based lubricants.
FIT
Trojan condoms come in three sizes: Regular; Large and Extra large. Trojan offers several varieties of large (magnum-sized) condoms: the MAGNUM®, the MAGNUM® Twister, the MAGNUM® Warming Sensation, the Trojan NaturaLamb and the MAGNUM® Thin condoms (the thinnest magnum condom available). There is only one variety of extra large condoms, the MAGNUM® XL Latex Condom, which is 30% larger than standard condoms.
DESIGN
* Standard designs include seven varieties: the Trojan-ENZ® Lubricated (‘jelly-like’ water-based lubricant); the Trojan-ENZ® Spermicidal Lubricated (Nonoxynol-9 spermicide, for protection against pregnancy); Trojan® Non-Lubricated; TROJAN® Extended Pleasure™ (lubricant with special additive to help prevent premature ejaculation and provide greater staying power); the TROJAN® Ultra Thin Latex Condom (over 25% thinner than standard condoms); TROJAN® THINTENSITY® (over 25% thinner than standard condoms, slightly longer and slightly larger at the closed end, ultra smooth lubricant and the TROJAN® Ultra Thin Spermicidal Lubricant Condom
* Extra Sensitive designs include six varieties: the TROJAN® Very Sensitive (uniquely shaped to enhance stimulation and sensitivity, lubricated); the MAGNUM® Thin condoms; the TROJAN® Ultra Thin Latex Condom; the TROJAN Supra®; the TROJAN® THINTENSITY®; and the TROJAN® Ultra Thin Spermicidal Lubricant Condom
* Mutual Stimulation designs include nine varieties: the TROJAN® Her Pleasure™ condom (unique texturing provides extra sensation for a woman, warming lubrication that is activated by natural body moisture); the TROJAN® Twisted Pleasure™ condom (designed with a twist at the closed end to help stimulate both partners, lubricated); the TROJAN® Ultra Pleasure condom (lubricated); the MAGNUM® Twister; the TROJAN® Ultra Pleasure® Spermicidal lubricant condom; the TROJAN® Her Pleasure™ (ribbed and contoured, lubricated); the TROJAN® Shared Pleasure™ condom (warming lubrication); the TROJAN® Her Pleasure™ condom (spermicidal lubricant)
* Roomier designs include larger sized condoms of different varieties.
* Textured designs: include the TROJAN® Her Pleasure™ condom (regular lubrication, with spermicidal lubrication or warming lubrication); TROJAN® Intense Ribbed® (comfortable shape and deep ribs at base and tip, lubricated); the TROJAN® Ultra Ribbed condom (deeper ribs, lubricated, also available with spermicidal lubricant); the TROJAN® Her Pleasure (spermicidal and regular lubricant)
* Warm Sensations designs include: the MAGNUM® Warming Sensation; and the TROJAN Supra® polyurethane condom.
Trojan condoms also come in several flavors: Mint Tingle, Sparkling Vanilla Gold, Tantalizing Tutti-Frutti, Rich Dark Chocolate and Sumptuous Strawberry.
All Trojan ultra thin condom varieties have an average thinness of about 00.20 of an inch, to increase sensitivity and make users feel the contraceptive device as little as possible. Trojan condoms, like all condoms, have a shelf life of about five years – though condoms with spermicidal lubricants have a three-year expiration date, but it’s the spermicides that are only effective for 3 years, not the condom itself.
General Condom Shapes
Reservoir Tip Condoms
These are regular condoms. The reservoir tip acts as a trap to collect semen.
Non-Reservoir Tip Condoms
These condoms feature a straight wall design without a reservoir tip. These are mostly used in the healthcare industry and for oral sex.
Form-Fitted Condoms
These condoms provide a better fit and more comfort.
Studded Condoms
These condoms have raised bumps for added sensation.
Ribbed Condoms
These condoms have raised lines on the shaft. These lines help in stimulation the vagina for added sensation.
Special Shaped Condoms
These condoms feature a “Baggy” pouch on the head. Condoms like the Twisted Pleasure use this pouch for extra stimulation. The extra headroom for him makes it less restrictive and better feeling. The excess “Bagginess” will hit upon her most sensitive regions to help in creating extra sensation.
