Hi Doctor, This Is Varsha I Got Married Recently,me N

hi doctor,
this is varsha
I got married recently,me n my husband are having sex everyday.. after marriage only once he was able to release semen inside my vagina. after that even though he tries hard to release semen inside my vagina but he was not able to release. Then he takes out Penis & then masturbates with hand,when the semen is about to come,he pushes inside my vagina and releases semen.
How to overcome this & will I get pregnant by doing this?
Could you please advice us?
I am 25 he is 32

Thanks
Varsha
