Dear sir, My name is Asim I am in UAE for more...

regarding penis swelling :
its expected to cause such a temporary side effects especially after hard masturbation, just avoid hard practice during masturbation and this symptom will be lighter 
- after all , this symptom is temporary and not harmful 
regarding sperm color :
normal sperm color is ranging from gray white to yellowish white , all are natural and doesnt mean you have more wbc or have disease 
regarding not being able to get wife pregnant in first months of marriage :
thats also totally normal condition, pregnancy chances in normal practice of sex usually only 25% per cycle 
- you would need to consult your doctor and do the needed tests for both partners if you have practiced and engaged sex without OC methods for a whole year and couldnt get pregnant 
what is the needed step now :
no specific advice is recommended as all your concerns are normal, we advice you and your partner to do the following :
1. make sure to do the sexual intercourse during the ovulation time to increase the chance of getting pregnant 
2. performing sexual intercourse many timeswont effect the quality of male semen , but in the same time ,  performing it in excessive way such as ( 3 times daily ) won't increase the chances of getting pregnant , so just try to perform sexual intercourse in mild range such as once daily and it's enough to get you pregnant 
3. lie down after sexual intercourse for about half an hour , and don't wash your private parts directly after that 
4. take care of your and your partner life style quality , eat healthier food , sleep well , avoid stress and anxiety , do exercise regulary
