my penis foreskin does not come back to glan automatically?

First of all, yes you will be able to have sex with a woman and be able to make her pregnant. A tight foreskin doesn't prevent you from doing any of that.

That said, sex probably won't feel as good for you because the most sensitive parts of your penis are always covered up by your foreskin. There are definitely things you can do yourself to loosen your foreskin. So ignore anyone who says you should get circumcised, that is NOT necessary.

The first thing you should try are "stretching exercises." In one stretching exercise, you basically "hook" one finger on either side of the foreskin and pull in opposite directions as if you're trying to increase the diameter of your foreskin's opening. Stretch and hold the foreskin for 10-20 seconds, then relax for 5-10 seconds, and then repeat for 10-20 minutes every day for maybe a month or so. It's best to do these exercises after a bath/shower when the skin's most flexible. It's important to be diligent about this and do it every day, but don't stretch too hard such that you rip or causes tears in your foreskin, as that'll scar up and make things worse in the long-run. See links 1 and 2 for good detailed instructions on what to do.

If after 3 months and you see little/no progress, then it's a good idea for you to ask your doctor for a prescription cream that helps loosen the foreskin (link 3). If you combine the prescribed cream with the stretching exercises above, the whole process will be quicker and easier.

In almost all cases of a tight foreskin the above treatments are all that's necessary. So you can ignore any suggestions or recommendations to get circumcised, as that's just not necessary. Worse comes to worst, there is an alternative surgery that removes little/no foreskin, is cheaper, is less painful, and has a quicker recovery time (link 4). However, not all doctors know or are skilled in this procedure, so it's important to find a doctor who's both willing and experienced in doing them.

See the remaining links for more useful info. You'll be fine, just do the above.

Foreskin problems and treatment

Many Teenaged boys suffer from tightness of foreskin. This is medically called Phimosis.

Start using some kind of medicated lubricating jelly (viz., K-Y lubricating jelly or Aloe Vera gel which is available in all medical shops) and slowly move the skin back and forth and sideways to bring the normal flexibility to the foreskin. This practice may bring your foreskin to normal after some days. Till the movement of skin becomes normal, you can use Lidocaine jelly 2% which is a local anaesthetic ointment.

If the skin is rough, you may have to go for circumcision surgery, as a lost resort. But circumcision is not at all necessary, as this poses many untold problems later during sex, such as loss of natural pleasure, unwanted irritation on sensitive glans penis, so on and so forth.

Always keep inside of foreskin clean by using a mild soap to avoid accumulation of smegma and the resultant offensive odour. You have to take care of this sensitive part more than your face.

Cracks will normally happen if you are in the habit of masturbating without using some kind of lubrication both on your penis and palms. When the penis becomes hard during Masturbation, you feel more pain if the foreskin does not retract.

You can apply an antiseptic ointment viz., Candid cream/Canesten cream if there is crack on the foreskin. Avoid moving the foreskin without using K-Y lubricating jelly or Aloe Vera gel or coconut oil.

It is also advisable to use pre-lubricated condoms to avoid spillage of semen all over the area and on your hands.

its quiet normal.

no doubt u can make pregnancy.
