Had no sex for three years and no masturbation only exercise will i b tight like virgin again?

Don't worry ...: I wouldn't worry about it before menopause. But ample foreplay followed with slow penetration and dilation will do the trick to resume sexual intercourse. Of course, partner has to understand and be gentle. At times, professional counseling and help may be required but rarely. So, at this time, I would not worry about it; enjoy your lifestyle without obsession whatever may suit you now. Best wish.
