Wow... 4 years? Damn long ler....
Maybe u wanna try to work it out with her? just maybe arrange for some "romantic" session that she will like and do something that make her feel touched. Then straight after the moves slow slow kiss her, pretend to promise her this time will be the same as the usual petting.
Then try all kinds of ways to make her feel aroused->well, i went thru a lot of experiment to find out my gf weakness spot - nipples. Just pretend tht u r not going into intercourse, kiss and lick her and pray hard that you get her weakness spot, then when she breathing hard and fast, continue, dun stop.
Then when u feel that she really cannot tahan liao, asked her softly in her ears if she wants to or not...
Then bingo!!!!!!
Juz my 2 cents tots....
