hiii mam,

You are 26 yrs old and spend 1yr of marriage life but your husband is suffering from difficulty in insertion of penis into vagina either slips or becomes small.
If your husband's penis is anatomically normal in appearance and erection & ejaculation occur outside the vagina by sexual stimulation or masturbation,then it is ok.
But if he does not initiate or maintain his erection,then probably suffering from "ERECTILE DYSFUNCTION" which may be worsed by stress,anxiety or depression.

**Guidline For Enjoying Sex Life with ED>>

1)I think that your vagina and other reproductive organs are anatomically normal and you are excited with sexual stimulation. "NARROW INTROITUS" or congenital anomaly may hamper with insertion of penis. So check it with consultation of gynaecologist.

2)Next step,Relax your husband by any means and keep away him from stress, anxiety or depression. Create romantic mood for special time with cool environment in bed room and try to maintain a cheerful life. This is very helpful to initiate and maintain cool sex life.

3)Next have to eliminate any underlying condition like diabetes,cardiac problem,hypertension,blunt trauma,fearness,hernia,phimosis along with related drugs.

4)Help him to initiate erection of penis,then prctice him to maintain erection for some times and ejaculation. All things to do outside the vagina and you have to play an important role to practise him before any sexual intercourse. This exercise should have to continue for 4 to 12 wks and help to treat mild to moderate degree of "ERECTILE DYSFUNCTION".

5)Avoid hot environment work place and wear loose fitting cotton underwear. Control body wt and take healthy diet.Quit smoke and alcohol if habit with it.

6)If above not responding,take VIAGRA (Sildenafil) - 1 hr before sexual intercourse.

All the best and enjoy healthy sextual life.
