I agree. There's NO need for him to frequently talk about previous sexual experiences to his current girlfriend. Thats pretty much Dating 101. You need to tell him how you feel if he loves you he will respect your feelings.
So, so you think you can tell Heaven from Hell,
blue skies from pain.
Can you tell a green field from a cold steel rail?
A smile from a veil?
Do you think you can tell?
And did they get you to trade your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
And did you exchange a walk on part in the war for a lead role in a cage?
