I’m pregnant, we haven’t had sex in 2 months

I’m 15 weeks, with our first baby girl. My boyfriend and I are actually doing amazing. Our communication has come SUCH a long way, from week 4 of pregnancy. However, we dont have sex anymore. We cuddle, kiss and show affection that way.. but we don’t make out or have any sexual encounters anymore. We’ve talked about it and he’s promised me he’s still attracted (he compliments me daily) but since we found out I was pregnant (it was unexpected) he says he’s pretty much lost his sex drive.. has anyone else experienced this?? Is there anything that helps? My sex drive has finally gone back up.. but his hasn’t.. help!!
