The sharp pains could be his penis hitting against your cervix. Also, sex is okay during pregnancy unless your doctor tells you no. And it's pretty normal to feel bad about "not pleasing your man" but he will just have to understand how you are feeling because for many women it only gets worse during the third trimester and when you begin to show. I haven't had sex with my husband in almost 10 weeks and I am due here any day and the doctor suggests not to have sex for 6 weeks after the birth of the baby. It's a normal feeling. But who knows? During the second trimester you might want to have sex every single day! It differs for people.
I was the same way only my dr had told me not to have sex untill he gave the say so because i was bleeding and cramping. But even after it was ok i didnt want to at all. I was sick all the time and just felt like crap. And oral for me was horrible i had tried but everytime i had to stop and go throw up so it didnt work out so well. About half way thru my 2nd trimester i was back in the mood and feeling better but it was short lived. It hasnt been till recently that ive wanted to have sex and now its like pulling teeth to get my boyfriend to sleep with me. I. Just hopeing that it doesnt stay like this after the baby is here
Cramping is normal after sex but idk about sharp pains during. Maybe just take it easy and talk to your dr about it. not wanting sex is also very normal it will come and go with pregnancy just talk to him about it. It's not your fault it's your hormones and body changing
