TMI dealing with feeling turned on

Ok so I'm feeling a lot embarrassed about this so please be gentle with me. I found out I am pregnant last week and eating to see if i can get a due date scan. Just before  finding out and even more so now I am getting moments of where I just want to have sex right there and then. Hubby is loving it but he isn't always around when I have them (he works regular 9-5job where as i do mostly shifts). Basically what I'm asking is how do I deal with the horniness when he isn't around. Don't like idea of sex toys and due to Raynaud's syndrome cold showers are a no go.
