I'm afraid my boyfriend might be gay.

I've been dating this guy for about a year and without intending to, I got pregnant and am now about 4 months along. I had always thought he had some interesting quirks and was a bit strange but didn't let it bother me too much. I have my own self-esteem issues and I am trying to parse out what's my deal and what his might be.

When I found out I was pregnant I began getting concern that sex would become a problem so I was thinking of new positions and maybe anal sex instead and he did not like the idea of having anal sex at all. I had also read about guys liking some anal play to hit their G-spot and he refused that as well and he finally said he was afraid he might like it. His dad had thought he was gay maybe 2 years ago and asked him straight out. He has never been in a serious long term relationship before being with me and he's 28 years old now. He lived alone for years, has pretty much all guy friends, plays basketball with them and does jijitsu with them. When I asked about some of his past sexual experiences he admitted that he's mainly had one night stands and didn't enjoy sex with his last g/f because he said she would just lie there. He's also had 2 different 3somes- one with 2 girls and he said it was awful and another 3some with a girl and his guy friend... he said he and his guy friend never touched but just the same it sounds awkward.

He mostly does things by himself like gardening, reading books, playing with his dogs and building things outside.

We do have sex (obviously) and we have sex often. He likes doggy style the best and when I go down on him.

So is he just odd and homophobic or should I be concerned??

Any comments are appreciated!
