Dry spell :-(

I havent had sex since i got pregnant. And im horny all the time. Ive seen my boyfriend twice, we are long distance, since we concieved and I understood that he had a lot of stress from taking 7 college classes and he didnt want to have sex..

But now he is coming down for the summer and i fear he will not have sex with me. And some how ill have to sneak away with my phone and vibrator and have EVEN MORE orgasms. Maybe its anxiety. But this dry spell is getting bad. And i just hear great things about sex when your pregnantm
