If some men really want to obligate women that are not attracted to them to sleep with them, then those men should also be obligated to sleep with gay men that are attracted to those men (that they are not attracted to). Sexual equality, right?

Women are much more vulnerable to STDs and infinitely more vulnerable to pregnancy.

Now if the risks are somehow equalized... unless you are going to say that it is not fair because you don't get exactly what you want... well women who are not attracted to you will never get exactly what they want either.
