You are using strfind incorrectly. You have to see if strfind returns -1 for it to be true. You should use strcmp instead.

Example

pawn Код:

if(!strcmp(inputtext,"America",true))
{
    SendClientMessage(playerid, -1, "You typed America in the dialog box!");
    return 1;
}

Another flaw in your code is the variable

pawn Код:

pData[playerid][pSex]

You need to make sure that that variable is a string in your Player Data enumerator.
I use this stock to replace a string.

pawn Код:

stock strreplace(string[], find, replace)
{
    for(new i=0; string[i]; i++) {
        if(string[i] == find) {
            string[i] = replace;
        }
    }
}

This is how it is used

pawn Код:

if(!strcmp(inputtext,"Male",true))
{
    SendClientMessage(playerid, -1, "So you are a Male!");
    strreplace(pData[playerid][pSex],pData[playerid][pSex],inputtext);
    // The first parameter gets the string
    // The second parameter basically selects the whole string
    // The last parameter replaces the whole string with the dialog inputtext.
    return 1;
}
