I can't count how many times I have been turned down by a female for sex when something else would have made a world of difference.
When a guy asks for SEX...give him s, or e, or just x ...that's not what he asked for..but it is ENOUGH for him to feel attractive, which is the most important part of that exchange, for both of you to feel sexy and attractive.
The sex will happen...like everything else, take it slow, but keep working at it...DONT" just IGNORE it.
