im having trouble with condom sizes. im 7.5x6.1 or so at the base, and ive tried a lot of different trojan condoms. regular lubricated, twisted pleasure, her pleasure, etc, and theyre all too tight on me at the base. it squeezes in waaay too tight and it makes me lose my erection. im thinking about trying trojan magnums since theyre only 0.3 inches longer than regular lubricated, theyre just a little wider. any suggestions?
