The length of penis depends on age as based on discussion in thod group.For thitythree year old male guy the mean size of penis is 7 cm without erection .when erected size is 9.5cm.the penis is conchy shaped.here considering erected penis the tip portion of penis forming cone shape .if touching around the cone part the inner muscles feel the presence.so this can make any problem while having sex with girl.moreover when penis is erected its not straight as flattened .it is touching abdomen.please give suggestions...am just worried...
