I agree with your thinking... I think that, men especially, but not only, get a desire to release their sexual desire. (In men, this is caused by the build up of seminal fluid in the seminal vesicles) It is also caused by testosterone as normal function of the body.
I'm not a woman so I have no idea what increases their need for sexual release, but without it.. we would never procreate.
To ask men to go until they are married, without a release... is a huge task..
Yes, I guess some can do it... However, telling some young men that this is a sin... is a stumbling block.
It would be quickly followed by... "Forget that... if that's what I have to do when I'm a Christian".
Again, I will ask... any man.... before you were married... and maybe after... are you saying you never lusted after a woman for sex? Or thought she was desirable in that way? Thought she was attractive?
Let's really be honest here guys...
